## How many moles of gas are in STP?

This makes for a very useful approximation: any gas at STP has a volume of 22.4 L per mole of gas; that is, the molar volume at STP is 22.4 L/mol (Figure 6.3 “Molar Volume”).

## How many moles of gas are in a volume of 48.6 L at STP?

1 Answer. 2.17 moles of gas.

## How can you calculate the moles of a gas in a given volume at STP?

Thus, at STP, the ideal gas law can be written V = 0.022414n. Divide the mass of the gas weight by its molar mass to calculate n — the number of moles. Nitrogen gas has a molar mass of 28 g/mole, so 56 g of the gas is equivalent to 2 moles.

37.8 moles

Helium

## How do you calculate N in PV?

FV = PV*[1+(i/n)] (n*t) At last, n’ represents the consecutive number of periods of interest per year. This particular formula also uses to figure out the present amount of value of the money you will receive in the future.

## What are the simple gas laws?

The volume of a given amount of gas sample is directly proportional to its absolute temperature at constant pressure (Charles’s law). The volume of a given amount of gas is inversely proportional to its pressure when temperature is held constant (Boyle’s law).

## What is a simple gas?

A gas is one of the four most common states of matter. In a gas the molecules move freely and are independent of each other. It may be elemental, where each molecule is made of more than one of the same atom bound together. It may be compounds where molecules are made of many types of atoms together.

## Does pressure depend on volume?

The pressure exerted by a static fluid depends only upon the depth of the fluid, the density of the fluid, and the acceleration of gravity. The most remarkable thing about this expression is what it does not include. The fluid pressure at a given depth does not depend upon the total mass or total volume of the liquid.
