Answer:

Step-by-step explanation:

Molecular weight of Be(OH)₂ = 43 .

One mole contains 2 atoms of oxygen . Atomic weight of oxygen is 16 so 2 atoms will have mass of 32 u .

So 43 g of Be(OH)₂ contains 32 g of oxygen .

100 g of Be(OH)₂ contains 32 x 100/ 43 g of oxygen

= 32 x 100/ 43 g of oxygen

= 74.42 % .
