b)0.5 of water ​

Answer 1

a). 2*32=6.4grm

b).5*18=9gram

Answer 2

☺ 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.

⭐ Mass of one mole of oxygen atoms = 16g Then, mass of 0.2 mole of oxygen atoms

= 0.2 × 16g = 3.2g

__________________________

⭐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______❤
