# Frequent question: How much is the volume of 3 5 moles of a gas?

Contents

## What is the volume of 3.5 moles of a gas?

What is the volume of 3.5 moles of oxygen gas (O2) at standard temperature and pressure (STP)? 6.4 L.

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

The molar volume of any gas is 22.4 dm3 mol-1 at STP or 24 dm3 mol-1 at room conditions. Note: STP refers to standard temperature of 0°C and pressure of 1 atmosphere. Room conditions refer to the temperature of 25°C and the pressure of 1 atmosphere.

## How do you find the volume of a mole with 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 is the volume of 5.00 moles of gas at STP?

The volume of 5.0 g CO2 is 2.6 L CO2 at STP.

## What is the volume of 2 moles of oxygen gas?

Assuming that the gas is at standard temperature and pressure (STP), one mole of any gas occupies 22.4 L . This means the number of moles of O2 is 222.4=0.089 mol .

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

3mol ⋅22.7 Lmol =68.1 L .

## What is the volume of 3 moles of oxygen at STP?

3 moles of oxygen at STP will occupy a volume of 3×22.

## How do I find the volume?

Whereas the basic formula for the area of a rectangular shape is length × width, the basic formula for volume is length × width × height.

## How do you find the volume of a gas given pressure?

The equations describing these laws are special cases of the ideal gas law, PV = nRT, where P is the pressure of the gas, V is its volume, n is the number of moles of the gas, T is its kelvin temperature, and R is the ideal (universal) gas constant.

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

What is the volume of 1 mole of an ideal gas at STP (Standard Temperature and Pressure = 0 °C, 1 atm)? 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 the volume at STP?

Standard temperature and pressure (STP) are a useful set of benchmark conditions to compare other properties of gases. At STP, gases have a volume of 22.4 L per mole.

## How many moles are in a liter at STP?

At Standard Temperature and Pressure (STP), 1 mole of any gas will occupy a volume of 22.4 L.
