## How do you convert 0.5 moles to grams?

In order to convert the moles of a substance to grams, you will need to multiply the mole value of the substance by its molar mass.

## How many grams are in 5.0 moles?

Therefore, 5 moles × 32.0 g/mol = 160 grams is the mass (m) when there are 5 moles of O2 .

## How many grams are in 2 moles of NH3?

The molecular weight of NH3 is 17. (14+1+1+1). So 1 mole of ammonia weighs 17 grams. Therefore 2 moles will weigh 34 gram.

## What is the number of atoms in 0.5 mol of ammonia gas?

0.5 moles of NH3 are present. 0.5×6.022×10^23 = 3.011×10^23 molecules of NH3. Each NH3 molecule has 4 atoms. Therefore the total number of atoms is 3.011×10^23 × 4 =12.044×10^23 atoms.

## How many atoms or molecules are in 5.0 moles of O?

Hence, number of moles of Oxygen in 5 Moles of CO = 5. The number of oxygen atoms present can be obtained by multiplying the moles of oxygen by Avogadro’s Number. So, number of oxygen atoms present = 5 x ( 6.023 x 10^23 ) = 30.115 x 10^23 nos.

## What is the molecular mass of O?

Divide the mass of the substance in grams by its molecular weight. This will give you the number of moles of that substance that are in the specified mass. For 12 g of water, (25 g)/(18.015 g/mol) = 0.666 moles.

## How many grams are in 0.2 moles of NH3?

Ammonia has a molecular weight of about 17, so 0.2 moles x 17 g/mol = 3.4 g of ammonia.

## How much mass is in 0.2 mole of NH3?

0.2 moles of atoms the weight will be 16*0.2 which is equal to 3.2 grams.

## How many molecules are there in 5 grams of NH3?

Avogadro said that 1 mole of any compound will contain 6.023 × 10²³ particles. That implies, 5 moles of NH3 will contain 5 × 6.023 × 10²³ NH3 molecules.

## How many atoms are there in 5 moles of NH3?

That implies, 5 moles of NH3 will contain 5 × 6.023 × 10²³ NH3 molecules. So, 5 moles of NH3 will contain 3 × 5 × 6.023 × 10²³ H atoms.

## How many atoms are there in 5 molecules of ammonia NH3?

There are four atoms in a molecule of ammonia.
