A total of 0.638 moles of neon are needed to occupy a volume of 14.3 L at standard temperature and pressure (STP).

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

The answer is 1100L .

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

2: A mole of any gas occupies 22.4L at standard temperature and pressure (0oC and 1atm). The figure below illustrates how molar volume can be seen when comparing different gases. Samples of helium (He), nitrogen (N2), and methane (CH4) are at STP.

## What is the volume of 3.5 moles of hydrogen gas at STP?

STP (standard temperature and pressure) which is 0oC 0 o C or 273 K and 1 atmosphere (New updates though define the pressure as 100,000 kPa or 0.987 atmospheres). At STP, 1 mole of an ideal gas will occupy a volume of 22.4 liters (Note: the new defined STP volume is 22.7 liters).

## How do you calculate the volume of a liter of gases at STP?

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. Record the molar gas constant “R”. R = 8.314472 J/mole x K.

## 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.

## What is the volume in dm3 of 3 moles of oxygen gas at STP?

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

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

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 1 mole of oxygen 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.

## What is the volume of oxygen at STP?

Thus volume of O2 required = 500 cm3 at S.T.P. According to Gay Lussac’s law of gaseous volumes.

## How do I calculate STP?

What is standard temperature and pressure?

- The standard temperature is equal to: 273.15 K = 0°C = 32°F ️ …
- The standard pressure is equal to: 1 atm = 760 Torr = 760 mm Hg = 101.35 kPa. …
- 1 mol of ideal gas in these conditions has a volume of 22.4 Liters.

## What is the volume of 3.5 moles of 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 2.5 moles of O2 at STP?

At STP (Standard Temperature and Pressure:0º C and 1 atm), 1 mole of gas takes up 22.4 L of volume. We’ll learn how to convert back and forth between moles and liters of a gas at STP. Avogadro’s Law is sometimes used as the name for the fact that 1 mole = 22.4 L at STP.

## What is the N in PV nRT?

The ideal gas law can also be written and solved in terms of the number of moles of gas: PV = nRT, where n is number of moles and R is the universal gas constant, R = 8.31 J/mol ⋅ K. The ideal gas law is generally valid at temperatures well above the boiling temperature.

## 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 do you find the volume of oxygen?

1 g = 1 / 217 = 4.608 × 10-3 mole. The number of moles of oxygen is half the number of moles of mercury oxide = 2.304 × 10-3. If the volume of one mole of gas is about 24,000 cm3, then the volume of oxygen obtained will be 2.304 × 10-3 × 24,000 = 55.3 cm3.
