Question

Find out the mass of 6.023× 1023 number of O2 molecule

Answer 1

Answer:

Explanation:

Molar mass of oxygen = 32 g/mol. Mass of 6.022 × 10^23 molecules of oxygen = 32 g. So, mass of 6.023 × 10^21 molecules of oxygen = {(6.023 × 10^21)/(6.022×10^23)} × 32 g = 1 × (10^-2 × 32) g = 0.32 g.
