1.	How many grams are therein: (i) 5 moles of water (ii) 2 moles of Ammonia (iii) 2 moles of Glucose
Answer» (i) 5 moles of water. Mass of 1 mole of water (H₂O) = 18 g (2 + 16) Mass of 5 moles of H₂O = 18 × 5 = 90 g. (ii) 2 moles of ammonia. Mass of 1 mole of ammonia (NH₃) = 17 g (14 + 3) Mass of 2 moles of ammonia = 17 × 2 = 34 g. (iii) 2 moles of glucose. Mass of 1 mole of glucose (C₆H₁₂O₆) = 180 g (72 + 12 + 96) Mass of 2 moles of glucose = 180 × 2 = 360 g.

How many grams are therein: (i) 5 moles of water (ii) 2 moles of Ammonia (iii) 2 moles of Glucose

Answer»

(i) 5 moles of water.

Mass of 1 mole of water (H₂O) = 18 g (2 + 16)

Mass of 5 moles of H₂O = 18 × 5 = 90 g.

(ii) 2 moles of ammonia.

Mass of 1 mole of ammonia (NH₃) = 17 g (14 + 3)

Mass of 2 moles of ammonia = 17 × 2 = 34 g.

(iii) 2 moles of glucose.

Mass of 1 mole of glucose (C₆H₁₂O₆) = 180 g (72 + 12 + 96)

Mass of 2 moles of glucose = 180 × 2 = 360 g.
