Question

find mass of .a-0.5 mass of oxygen,,,,b-0.5 moles of o atoms

Answer 1

0.5 mol of oxygen


oxygen=o=16u=16g=1mol

0.5 mol=16g/2
=8g

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 O = 16g Then, mass of 0.5 mole of o

= 0.5 × 16g = 8g

I hope, this will help you.

Thank you______❤
