Question

Calculate the molecular mass of the following (a)H2CO3 (b)C2H50H​

Answer 1

Answer:

Explanation:

Atomic mass of hydrogen is 1 carbon is 14 and oxygen is 16.

So the molecular mass of h2co3= 2+14+48 = 64 unit..

2. Atomic mass of carbon is 14 hydrogen is 1 and oxygen is 16.

So the molecular mass of c2h5oh = 28 + 5 + 16 + 1 = 50 unit..

3. Atomic mass of magnesium is 24 sulphur is 32 and oxygen is 16.

So the molecular mass of mgso4 = 24 + 32 + 64 = 120 unit

Answer 2
