Question

4. Calculate the relative molecular masses of the following substances [RAM: H=1, O=16, S=32, C=12, N=14] a. CH2(NH2)COOH b. H2SO4​

Answer 1

Answer:

a. CH2(NH2)COOH

$molecular \: mass = (12 \times 2) + (5 \times 1) + (14 \times 1) + (16 \times 2) \\ = 24 + 5 + 14 + 32 \\ = 75 \: grams$

b. H2SO4

$molecular \: mass = (2 \times 1) + 32 + (16 \times 4) \\ = 2 + 32 + 64\\ = 98 \: grams$
