How would you determine the proper number of significant figures for the volume of liquid using your measuring equipment?
How would you determine the proper number of significant figures for the volume of liquid using your measuring equipment?
You determine the correct number of significant figure of a measurement in a graduated cylinder by looking at the smallest division on the graduated cylinder. If the division is divided up to the ones place, you can still read the half of that division or the .
How do you determine the number of significant figures when you make a measurement?
Use the least number of significant figures past the decimal point when adding or subtracting numbers. For example, the answer to 123.45 + 543.2 would have 1 significant figure past the decimal point.
How many significant figures can liquid density be properly reported?
three significant figures
How many significant figures do you have to use when using a 10 mL graduated cylinder to measure the volume of a sample that is less than 10 MLS?
2 decimal places
How do you read a 50 mL graduated cylinder?
With a 50-mL graduated cylinder, read and record the volume to the nearest 0.1 mL. The 10-mL graduated cylinder scale is read to the nearest 0.01 mL and the 500-mL graduated cylinder scale is read to the nearest milliliter (1 mL). A buret is a scaled cylindrical tube attached to a stopcock, or valve.
Which has greater precision the 10 mL graduated cylinder or the 50 mL graduated cylinder?
Answer Expert Verified The cylinder with the greater precision is the 10 ml graduated cylinder. The 50 ml graduated cylinder on the other hand has marks for every 1 ml, this graduation will only allow the user to record measurement up to one significant figure.
What volume is shown in this graduated cylinder?
Explanation: On this graduated cylinder there are 5 tick marks from 10 mL to 15 mL, so each tick mark represents 1 mL. The bottom of the meniscus is halfway between the tick marks representing 13 and 14 mL, so the best estimate of the volume is 13.5 mL.
What are the lines on a graduated cylinder called?
This curve is called the meniscus. Always read the measurement at the bottom of the meniscus. The graduated cylinder will usually have heavy markings at 10, 20, 30 . . . milliliters.
How do you read a graduated cylinder?
Reading a Graduated Cylinder Place the graduated cylinder on a flat surface and view the height of the liquid in the cylinder with your eyes directly level with the liquid. The liquid will tend to curve downward. This curve is called the meniscus. Always read the measurement at the bottom of the meniscus.
How do you read a graduated cylinder by 100?
In the 100-mL graduated cylinder shown, the labeled graduations are 60 and 50 mL. So, subtract 60 mL – 50 mL = 10 mL. Next, count that there are ten intervals between the labeled graduations. Therefore, the scale increment is 10 mL/10 graduations = 1 mL/graduation.
Does a graduated cylinder measure mass?
The volume of a liquid can be measured directly with a graduated cylinder. The molecules of different liquids have different size and mass. The mass and size of the molecules in a liquid and how closely they are packed together determine the density of the liquid.
What does Volumeter measure?
: an instrument for measuring volumes (as of gases or liquids) directly or (as of solids) by displacement of a liquid.
What are the two things a measurement must include?
All measurement involves two parameters: the amount present (i.e., the number) and the unit within a system of measurement.
When measuring the volume of the marble Why is it better to use the 25 mL graduated cylinder than the 100 mL graduated cylinder?
Explanation: A marble is not a very large object, so a smaller graduated cylinder is a better choice. A 100 milliliter graduated cylinder is not needed to measure the volume of a small marble, so a 25 milliliter graduated cylinder is the best option.
How many decimal places do you read a 10 mL graduated cylinder?
4 significant digits
How do you determine significant figures examples?
All non-zero digits are considered significant. For example, 91 has two significant figures (9 and 1), while 123.45 has five significant figures (1, 2, 3, 4, and 5). Zeros appearing between two non-zero digits (trapped zeros) are significant. Example: 101.12 has five significant figures: 1, 0, 1, 1, and 2.
What is the maximum number of significant figures that graduated cylinder can be reported to?
The maximum number of significant figures of the volumes that can be reported are 2; because its capacity is 50 ml, so it has 2 significant digits itself.
