Question

1g of a metal m (specific heat equals to 0.060205) combines with oxygen to form 1.08g of oxide. what is the atomic mass of m. what is its valency?​

Answer 1

Answer:

Acc to peeti,sand deulong law atomic weight×specific heat=6.4

Explanation:

Atwt=6.4/specific=6.4/0.060205=111.2(approximately)

Acc to weight/equivalent relation,weight/equivalent of metal=weight/equivalent of oxygen

1.08gof metal oxide means 1g of metal 0.08g of oxygen[equivalent weight of oxygen=8)

1/equivalent weight of metal=0.08/8,equivalent weight of metal=100

So the valency is 1
