Question

Calculate the molecular mass of the compound

☆Na2Co3




☆H2SO4 =??


☆CH3COOH = ??


☆HNO3 = ?​

Answer 1

Answer:-

Molecular mass as following compounds

$\sf{Na_{2}Co_{3}}$

• = 23 x 2 + 12 + 16 x 3
• = 46 + 12 + 48
• = 106

$\sf{H_{2}SO_{4}}$

• = 1 x 2 + 32 + 16 x 4
• = 2 + 32 + 64
• =98

$\sf{CH_{3}COOH}$

• = 12 + 1 x 3 + 12 + 16 + 16 + 1
• = 12 + 3 +12 + 16 + 16 + 1
• = 60

$\sf{HNO_{3}}$

• = 1 + 14 + 16 x 3
• = 1 + 14 + 48
• = 63
