Question

Find the ratio by mass of the following compounds: a) CaO b) MgCl2 c) H2S d) CO e) MgS f) NaCl

Answer 1

Answer:

5:2 , 24:35 , 1:32 , 3:4 , 3:4 , 23:35.

Explanation:

The ratio of the masses of the following compounds will be :-

a) For CaO we know that molar mass of Ca is 40 unit and of oxygen is 16 unit so the ratio is 5:2.

b) For MgCl2 we have molar mass of Mg as 24 and molar mass of chlorine as 35 so the ratio of the compound will be 24:35,

c) For H2S we have molar mass of hydrogen as 1 and molar mass of sulfur as 32 so the ratio of the compound will be 1:32.

d)For CO we have molar mass of carbon as 12 and molar mass of oxygen as 16 so the ratio of the compound will be 3:4.

e) For MgS we have molar mass of Mg as 24 and molar mass of sulfur as 32 so the ratio of the compound will be 3:4.

f)For NaCl we have molar mass of Na as 23 and molar mass of chlorine as 35 so the ratio of the compound will be 23:35.

Answer 2

24g Mg combine with 71g Cl to give-

$95g \: MgCl_{2}$
