Question

calculate the mass in grams for the following
1. 2.25 Mole of water
II. 0.2 mole of chlorine
Ill. 2 mole of Oxygen​

Answer 1

Answer:

1 mole of hydrogen atoms got 1 gram, so 2 moles of them got 2 grams. 1 mole of oxygen atoms got 16 grams. Therefore, 1 mole of H2O got 18 grams. 2 moles of H2O gets you 36 grams.

Chlorine gas Cl 2, has a relative molecular mass of 71 because it is made up of two Cl atoms, each of Mr 35.5.

63.9976 g

per mole of oxygen. From here, the answer is simple. Just multiply 2 by 31.9988 g because there are two moles of oxygen. So, the answer is 63.9976 g

Explanation:

Answer 2

Answer:

3.2 grams

Explanation:

To calculate the mass of 0.2 moles of oxygen atoms we should know the mass of single atom of oxygen that is 16.-Therefore, the mass of 0.2 moles of oxygen atom is 3.2 grams and the mass of 0.5 mole of water molecules is 0.9 grams.
