Question

The absolute mass of one molecule of a substance is 5.32X10-23g. What is its molecular mass ? What could this substance be ?

Answer 1

Hyyy




Mass of one molecule of substance = 5.32 x 10-23g

Hence mass of 6.022x1023 molecules of substance = 5.32 x 10-23 x 6.022x1023 = 32 g

Mass of the given substance is 32 u.

Oxygen has molecular mass of 32 u with formula O2


Hope helped

Answer 2

Hiiii


Here is the answer

5.32 x 10-23 x 6.022x1023 = 32 g

Mass = 32 u.

Oxygen has molecular mass of 32 u with formula O2
