## How do you find the volume of a mole with gas?

**Calculating the volume of a gas**

- Volume = amount in mol × molar volume.
- Volume = 0.25 × 24.
- = 6 dm

## How much volume does a mole take up?

1 mol of any gas at STP has a volume of **22.4 L**.

## 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 calculate the volume of a gas?

It can be written as: **V = nRT/P**. “P” is pressure, “V” is volume, n is the number of moles of a gas, “R” is the molar gas constant and “T” is temperature.

## What is the relationship between volume and moles?

A plot of the effect of temperature on the volume of a gas at constant pressure shows that **the volume of a gas is directly proportional to the number of moles of that gas**. This is stated as Avogadro’s law.

## How do I calculate moles?

**How to find moles?**

- Measure the weight of your substance.
- Use a periodic table to find its atomic or molecular mass.
- Divide the weight by the atomic or molecular mass.
- Check your results with Omni Calculator.

## What units are used in PV nRT?

**The units used in the ideal gas equation that PV = nRT are:**

- P is pressure measured in Pascals.
- V is the volume measured in m. …
- n is the number of moles.
- R is the universal gas constant measured in J/(K. mol)
- T is the temperature measured in Kelvin.

## What are the 5 assumptions of an ideal gas?

The kinetic-molecular theory of gases assumes that ideal gas molecules (1) are constantly moving; (2) have negligible volume; (3) have negligible intermolecular forces; (4) undergo perfectly elastic collisions; and (5) **have an average kinetic energy proportional to the ideal gas’s absolute temperature**.
