## What is the mass of 0.5 mole of oxygen?

That is, mass of one mole of a set molecules is gram molecular mass of that molecule. For example, molecular mass of a water molecule is 18 amu (2 amu for 2 hydrogen atoms, and 16 amu for one oxygen atom). So, mass of one mole of water would be 18 grams. Thus, mass of 0.5 moles of water would be 9 grams.

## What is the mass of 0 2?

a) Well, first of all 16 u = the mass of 1 mole of O2 atom. That is it weighs 16 g. ∴ Mass of 0.2 mole of O2 atoms = 16*0.2 = 3.2 u. Here ‘u’ refers to unified atomic mass unit.

## What is the mass of 0.1 mole of oxygen gas?

Mass of 0.1 mole of oxygen is = 16 * 0.1 =1.6 g.

## What is the mass in gram 1.5 mole of oxygen gas?

of oxygen atoms = 1.5 × 6.022×1023 = 9.033×1023 atoms Mass of Oxygen atoms = 1.5 × 16 = 24 g.

## What is the mass of 1 mole of bricks?

We’re being asked to calculate for a) the mass of 1 mole of brick and b) moles of bricks if its mass is equal to the mass of the Earth. The mass of 1 mole of brick is 2.4 x 1027 g.

## How many atoms are in a mole of oxygen?

1.4.

For one gram atomic weight of oxygen with atomic weight of 16 grams, one mole of oxygen also contains 6.022 × 1023 oxygen atoms.

## What is the number of molecules present in 1 mole of oxygen gas?

One mole of oxygen gas, which has the formula O2, has a mass of 32 g and contains 6.02 X 1023 molecules of oxygen but 12.04 X 1023 (2 X 6.02 X 1023) atoms, because each molecule of oxygen contains two oxygen atoms.
