It varies with container, temperature, pressure and amount of gas. But, the volume occupied by a gas at a fixed temperature and pressure remains constant which is 22.4 L for 1 mole at STP.

## What volume does .25 moles of oxygen gas occupy at STP?

Ernest Z. At STP (0 °C and 100 kPa), the volume of O₂ is 5.7 L. We can use the Ideal Gas Law to solve this problem.

## What is the volume of 0.25 moles of gas at STP?

If it’s at room temperature and pressure, then 1 mole of any gas occupies a volume of 24 L. Hence, for STP: 1 mole = 22.4 L/ 0.25 mole = x/ x = 5.6 L. At room temperature and pressure: 1 mole = 24 L/ 0.25 mole = x/ x = 6 L. 0.25 x 22.4 = 5.6L at STP.

## What is the volume of 0.025 mol O2 at STP?

0.025 moles = 0.025 X 22.4 l at s.t.p.

## What is the volume of 0.25 moles of co2 at STP?

Answer: Volume = 12.48 lit.

## What properties of gas is 273.15 at STP?

Note the International Union of Pure and Applied Chemistry (IUPAC) applies a more stringent standard of STP as a temperature of 273.15 K (0 °C, 32 °F) and an absolute pressure of exactly 100,000 Pa (1 bar, 14.5 psi, 0.98692 atm).

## How many moles are there in 40 Litres of CO2 at STP?

Answer: AT STP, 40 L CO2 will contain about 2 moles CO2.

## How many molecules are in 0.25 mole of o2?

Thus, 0.25 mole of oxygen contains 1.505×1023 1.505 × 10 23 molecules.

## How many grams of Co2 are present in 0.25 mole?

Answer:Gmm of Co2=(14+32)=46. =11.5 g.

## Which condition is STP?

Since 1982, STP is defined as a temperature of 273.15 K (0 °C, 32 °F) and an absolute pressure of exactly 10^{5} Pa (100 kPa, 1 bar).

## What is the volume occupied by 20 moles of O2 at STP?

Hence, the volume occupied by 20 g of oxygen at STP = 20×22.432 = 14 litres.

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

Hence, gram molecular volume of oxygen gas at STP is $22400{text{ c}}{{text{m}}^3}$ and the correct option is (C). Note: The value of pressure, temperature, moles and R should be taken with a proper unit system. The value of universal gas constant (R) should be taken with similar units as of pressure and volume.

## What is the volume occupied by 0.25 moles of nh3 gas at STP?

0.25 mole of the gas will occupy 224001×0.25 mL=5600 mL.

## What quantity of gas is contained in 28.0 L at STP?

The volume of 28.0 g of nitrogen gas at STP is 22.4 liters. Nitrogen gas has a density of 1.25 g/L at standard temperature and pressure (STP).

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

David G. 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 .

## How do you calculate the molar volume of a gas?

Calculating the volume of a gas

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