# Your question: What is the volume in dm3 of 3 moles of oxygen at STP?

Contents

## What will be the volume of 3 moles of oxygen gas at STP?

Answer: 3 moles of oxygen at STP will occupy a volume of 3×22. 4=67. 2 L.

## What is the volume of 3 moles of a gas at STP?

Multiply 3 moles by 22.4 Liters / mole, and the answer is 67.2 Liters. If you have a mixture of multiple gasses, calculate separately the volume of each component as if it were by itself, and then add them. This is because pressure and temperature are held constant at STP, so the total volume is conserved when mixing.

## What is the molar volume of 3 moles of He at STP?

Well, assuming that the hydrogen gas is contained at STP , then the molar volume would be 22.7⋅3=68.1 L .

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

Finally, use the fact that one mole of oxygen would occupy a volume of 22.4 L at STP to figure out the volume of the oxygen in this question at STP. The answer is 0.338 L (338 mL), but you will have to show the calculations to receive credit on your lab report.

## What is the volume of 0.5 moles of gas at STP?

0.5 moles⋅22.4 L/mol=11.2 L , and so on.

## What is molar volume of gas?

The molar volume is the volume occupied by one mole of any gas, at room temperature and pressure. The molar volume is equal to 24 dm 3 (24,000 cm 3). This volume is given in questions that need it.

## What is the volume of 3 moles of gas?

So, if 1 mole occupies 22.4 L, the imediate conclusion is that a bigger number of moles will occupy more than 22.4 L, and a smaller number of moles will occupy less than 22.4 L. In your case, 3 moles of gas will occupy 3 times more volume than 1 mole of gas.

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

So, the volume of an ideal gas is 22.41 L/mol at STP. This, 22.4 L, is probably the most remembered and least useful number in chemistry.

## What is STP molar volume?

Standard temperature and pressure (STP) is defined as 0oC (273.15K) and 1atm pressure. The molar volume of a gas is the volume of one mole of a gas at STP. At STP, one mole (6.02×1023 representative particles) of any gas occupies a volume of 22.4L (figure below). Figure 10.13.

## What is the volume of 1 moles of helium at STP?

A pressure of one atmosphere and a temperature of 0°C is known as standard temperature and pressure (STP). Under these conditions, one mole of any gas takes up a volume of 22.4 liters. This information allows us to convert between liters and moles for gases at STP. At STP, we have 46.2 liters of helium.
