Question

What is the weight of 10²³ molecules of sulphur dioxide​

Answer 1

Answer:

= 192.031 g

Explanation:

Molecular mass of SO2 = [32 + (2x16)] u

=> [32 + 32] u => 64 u

So,

Mass of 6.022 x 1023 number of molecules of SO2 = 64 g

Mass of 1 molecule of SO2 =

64/6.022x1023 g

Mass of 18.069 x 1023 molecules of SO2 = (64 x 18.069 x 1023/(6.022 x 1023) g

=> 192.031 g
