Enthusiastic about student learning! 11.2 L of the CO (carbon monoxide) gas is equivalent to 0.5 moles of it at STP. It’s a fact that one mole of ANY gas at STP occupies 22.4 L of space, so 11.2 L = 0.5 moles.

## How many atoms of oxygen are there in 11.2 L CO2 at STP?

of carbon and oxygen atoms present in 11.2 litres of CO_(2) at N.T.P. ∴3.011×1023 molecules of CO2 will contain oxygen atoms =2×3.011×1023=6.022×1023 atoms.

## How many moles of CO2 does STP have?

Since each mole produces 1 mole of CO2, 1.15 moles of CO2 will be formed. We can compute the volume of CO2 at STP by using the molar volume. 1.15 mol of CO2 x 22.42L CO2/ 1mol CO2 = 25.78 L of CO2 at STP.

## How many moles are in 11.2 l of hydrogen gas at STP?

1 mole of a gas has 22.4 L of volume at STP. Therefore, 0.5 mol of H_{2} has 0.5 x 6.022 x 10^{23} = 3.011 x 10^{23} molecules. Hence, the number of moles, molecules and atoms present in 11.2 liters of H_{2} at STP are 0.5 , 3.011 x 10^{23} and 6.022 x 10^{23} respectively.

## How many moles are in 2.5 L of CO2 at STP?

1 Expert Answer

2.50L x 1 mol/22.4 L = 0.112 moles CO_{2}.

## How many moles are in 11.2 l of CO2 gas at STP?

Enthusiastic about student learning! 11.2 L of the CO (carbon monoxide) gas is equivalent to 0.5 moles of it at STP. It’s a fact that one mole of ANY gas at STP occupies 22.4 L of space, so 11.2 L = 0.5 moles.

## How many moles are in 11.2 L of o2 gas at STP?

2 Answers By Expert Tutors

0.5 moles x 32 g/mole = 16 g.

## How many liters of CO2 are produced at STP?

At STP, a mole of gas takes up 22.4 liters. So the dioxide carbon producted will be 0.67/2 moles. Or, it will be 15/2 = 7.5 liters.

## How many moles are in STP?

At Standard Temperature and Pressure (STP), 1 mole of any gas will occupy a volume of 22.4 L. The Ideal Gas Law, along with a balanced chemical equation, can be used to solve for the amount, either in volume or mass, of gas consumed or produced in a chemical reaction.

## 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 mass of 11.2 l of hydrogen gas at STP?

The mass of 11.2 litres of a certain gas at s.t.p. is 24 g.

## How many moles are in 11.2 liters of hydrogen gas at STP group of answer choices?

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

## Which quantity of H2 gas has a volume of 11.2 L at STP?

1 mole of any gas at STP (standard temperature and pressure) occupies volume of 22.4 dm^3 or 22.4 liters. 11.2 L is half of 22.4 L, thus the number of moles are also halved.
