What is the relative mass and charge of each subatomic particle?
What is the relative mass and charge of each subatomic particle?
The relative mass of a proton is 1, and a particle with a relative mass smaller than 1 has less mass….Subatomic particles.
| Subatomic particle | Relative mass | Relative charge |
|---|---|---|
| Proton | 1 | +1 |
| Neutron | 1 | 0 |
| Electron | 0.0005 | -1 |
How would you compare the charges masses and locations of the subatomic particles?
Electrons surround the nucleus and have a negative charge and small mass relative to protons and neutrons Most of an atom’s mass Is In its nucleus, which is near the center and is composed of protons and neutrons Protons have a positive charge; neutrons have no charge.

What is the difference between relative atomic mass and average atomic mass?
Relative and average atomic mass both describe properties of an element related to its different isotopes. However, relative atomic mass is a standardized number that’s assumed to be correct under most circumstances, while average atomic mass is only true for a specific sample.
What is the unit for relative atomic mass?
amu
What is the relative formula mass of co2?
The molecular mass of carbon dioxide is 44.01amu. The molar mass of any compound is the mass in grams of one mole of that compound. One mole of carbon dioxide molecules has a mass of 44.01g, while one mole of sodium sulfide formula units has a mass of 78.04g. The molar masses are 44.01g/mol and 78.04g/mol respectively.
How do you calculate formula mass?
Explanation: To calculate formula mass, multiply the subscript of each element in the formula by the element’s atomic weight (relative atomic mass) found on the periodic table. The unit for formula mass is either u or Da (Daltons). The amu has been replaced with u, even though it is still commonly used.
What is the relative formula mass of Na2CO3?
106 g/mole
What is the relative formula mass of C6H12O6?
i.e. mass of 1 mole of glucose, C6H12O6 = (6 × 12.01 + 12 × 1.01 + 6 × 16.00) g = 180.18 g (using atomic weight data to 2 decimals) 1 mole of carbon atoms weighs 12.01 g and there are 6 moles of C atoms in 1 mole of glucose, so the mass of carbon in 1 mole of glucose = 6 × 12.01 g = 72.06 g.
