Question

element a reacts with a oxygen to for a compound a2o3. if 0.359 g of a reacts to give 0.559 gram of compoung, atomic weight of a in amu will be

Answer 1

Answer:

43.08gm

Explanation:

Compound is A²O³. Hence valency of A is 3.

Given weight of A= 0.359g

Wt. of its oxide = 0.559g

Wt. of Oxygen in oxide = 0.200g

Eq wt of A = wt of element * 8

wt of oxide

= 0.359 * 8 = 14.36

0.200

At wt of A = Eq wt * valency = 14.36 * 3 = 43.08gm
