Question

find mass of 1•5 × 10 ^26 molecules of So2 (in kg)​

Answer 1

Answer:

9.6 x 10^22 kg

Explanation:

mol mass of SO2 = 1*S +2*O = 1*32 + 2*16 = 32+32= 64g

total mass of 1.5 x 10^24 molecules = 64 x 1.5 x 10 ^24g = 96 x 10^24 g

                                                           = 96 x 10^21 kg = 9.6 x 10^22 kg
