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

**Molar volume of gases**

- volume = 0.5 × 24 = 12 dm
^{3} - Remember that 1 dm
^{3}= 1 000 cm^{3}so the volume is also 12 000 cm^{3} - The equation can be rearranged to find the number of moles, if the volume of gas at rtp is known:
- 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**

- P = pressure.
- V = volume.
- n = number of moles.
- T = temperature.
- 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.
