Given: 0.2 moles of water.
To find: We have to find the mass.
Solution:
The chemical formula of water is .
The atomic mass of H is 1 and the atomic mass of oxygen is 16.
Thus the molecular mass of water is 2×1+16=18 grams.
We can write,
One mole of water has a mass of 18 grams.
Thus 0.2 moles of water has a mass of 18×0.2=3.6 grams.
Thus the mass of 0.2 moles of water is 3.6 grams.
