## What is the mass of 0.5 mole of O2 gas?

0.5 moles of O2 weighs 16 grams.

## What is the mass of 0.5 moles?

Thus, the mass of 0.5 mole of water (H2O) is 9 grams.

## What is the mole of oxygen?

The mass of oxygen equal to one mole of oxygen is 15.998 grams and the mass of one mole of hydrogen is 1.008 g.

## What is the number of molecules in 0.25 moles of oxygen?

0.25 moles of oxygen there is 6.023/4×10^23 molecules.

## How many grams are in 4 moles of oxygen?

4 moles of oxygen gas would be equivalent to 4 moles x 32 g/mole = 128 g. Thus, 4 moles of oxygen gas (O2) would have a mass of 128 g.

## What is the formula for 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.

## What is 0.5 mole water?

Mass of 0.5 mole of water is 9g.

## What is the mass in gram of 5 moles of water?

Since one mole of water is made of two moles of Hydrogen (1.01 g/mol) and one mole of Oxygen (15.99 g/mol) its mass would be 18.01 g. Five moles of water whould have a mass of 90.05 g. One molecule of water weighs 18 AMU. If the number of water molecules is Avogadro’s number, it would be one mole of water.

## How do you find the mass of 0.5 moles of water?

Mass of 0.5 mole of H2O molecule = (18 x 0.5) u =9 u.

## How many moles are equal to 15 grams of oxygen?

So the answer would be (23.584-22.347)grams divided by 16.000 g/mol, or 7.7313×10^-2 moles O2.
