Question

The molecular formula of certain compound is M4O6. If 18.88g of the compaund contains 10g
of M the atomic mass of M is approximately​

Answer 1

The atomic mass of M = 27 u.

Explanation:

Given, 18.88g of the compound M_4O_6  contains 10g M

18.88g M_4O_6 contains 8.88g O

Thus,

According to above two expression ratio of M with O will be given as

4M : 6O = 10.0 : 8.88

Molar mass of the 6O a = 96 g/mol

Thus, mass of 4 M can be determined

4 M / 96 = 10.0/8.88

⇒4 M = (96 × 10)/8.88

⇒4 M = 108

⇒ M = 27

Hence, atomic mass of M = 27 u.
