☺ Hello mate__ ❤
◾◾here is your answer...
Approach to solving Question :- first we calculate mass of 1 mole. After this multiplying this by given no. Of mole.
(a) Mass of one mole of oxygen atoms = 16g Then, mass of 0.2 mole of oxygen atoms
= 0.2 × 16g = 3.2g
(b)Mass of one mole of water molecule = 18g Then, mass of 0.5 mole of water molecules
= 0.5 × 18g = 9g
I hope, this will help you.
Thank you______❤
