## How do you find the number of moles in a gas?

Molar volume of gases

1. volume = 0.5 × 24 = 12 dm 3
2. Remember that 1 dm 3 = 1 000 cm 3 so the volume is also 12 000 cm 3
3. The equation can be rearranged to find the number of moles, if the volume of gas at rtp is known:
4. number of moles = volume of gas at rtp ÷ 24.

## What form of the ideal gas law would you use to calculate the number of moles of a gas apex?

the ideal gas can also be writen and solved in the terms of number of moles of gas:pv =nRT,where n is number of moles and R is the universal gas ,R=8.31j/mol. k. the ideal gas law is generally valid at temperatures well above the boling temperature.

## What is the T in PV nRT?

PV = nRT is an equation used in chemistry called the ideal gas law equation. P = pressure of the gas. V = volume of the gas. n = number of moles of the gas. T = Temperature expressed in units of Kelvin.

## How do you find pressure in ideal gas law?

The ideal gas law formula states that pressure multiplied by volume is equal to moles times the universal gas constant times temperature.

Ideal Gas Law Formula

1. P = pressure.
2. V = volume.
3. n = number of moles.
4. T = temperature.
5. R = gas constant.

## What does the ideal gas law state?

The ideal gas law states that the pressure, temperature, and volume of gas are related to each other.

## What is the formula for moles to grams?

Moles to grams example problem

Solution: Find out the molar mass of the substance (hint: you can use Molar mass of the substance alone to calculate molar mass). The molar mass of KClO3 is 122.548 g/mol. Multiply the given number of moles (2.50 mol) by the molar mass (122.548 g/mol) to get the grams.
