Question

Find the gram molecular mass of the following from the data given:i) H2O ii) CO2 iii) NaOH iv) NO2 v) H2SO4

Philoid · Accepted Answer

Molecular mass is the sum of the atomic masses of all the atoms present in one molecule of the substance.

1. H₂O = (1gX2) + 16g = 18g

2. CO₂ = 12g + (2 x16g) = 12 + 32 = 44g

3. NaOH = 23g + 16g + 1g = 40g

4. NO₂ = 14 + (2 x 16) = 46g

5. H₂SO₄ = (1gx2) + 32g + (4x16g) = 98g
