## What describes the volume of 1 mol of gas at standard temperature and pressure?

22.41 L

The conditions 0°C (273.15 K) and 1 atm pressure for a gas. The volume of 1 mol of an ideal gas at STP (0°C and 1 atm pressure), which is 22.41 L.

The volume of a given 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).

**Which statement is correct the volume of 1 mol of CO2?**

Calculate volume of CO2 produced. The volume of one mole of CO2 produced is 24 dm^3 at room temperature and pressure. Alternatively, if your reaction took place at standard temperature and pressure (273 K, 1 atm), then the molar volume is 22.4 dm^3.

**Which describes the volume of 1 mole of gas?**

Which describes the volume of 1 mol of gas at standard temperature and pressure? The volume is the same for any gas.

### What is the volume at STP for 1 mole of a gas?

22.4L

At standard temperature and pressure, 1 mole of any gas occupies 22.4L.

### Which of the following is constant for 1 mole of any ideal gas?

constant R

The value of the proportionality constant R, can be calculated from the fact that exactly one mole of a gas at exactly 1 atm and at 0 ˚C (273 K) has a volume of 22.414 L.

**Does volume depend on the mass of a gas?**

The volume is greater for a larger mass of gas. The volume is the same for any gas. The volume depends on the size of the container. The volume varies with the pressure. The volume is the same for any gas.

**What is the volume occupied by 2 moles of an ideal gas?**

So, if you are given these values for temperature and pressure, the volume occupied by any number of moles of an ideal gas can be easily derived from knowing that 1 mole occupies 22.4 L. V = n ⋅ V molar For 2 moles of a gas at STP the volume will be 2 moles ⋅ 22.4 L/mol = 44.8 L

#### Why would knowing the molar volume of a gas be important?

Why would knowing the molar volume of a gas be important? The molar volume of a gas expresses the volume occupied by 1 mole of that respective gas under certain temperature and pressure conditions.

#### What is the molar volume of a gas at STP?

The most common example is the molar volume of a gas at STP (Standard Temperature and Pressure), which is equal to 22.4 L for 1 mole of any ideal gas at a temperature equal to 273.15 K and a pressure equal to 1.00 atm. * 22.4# #”L/mol” = 11.2# #”L”#, and so on.
