Convert into mole:(a) 12 g of oxygen gas(b) 20 g of water(c) 22 g of c

1.	Convert into mole:(a) 12 g of oxygen gas(b) 20 g of water(c) 22 g of carbon dioxide
Answer» (a) 32gm of oxygen means 1 mole 12gm oxygen means \(\frac{12}{32}\) mole ∴ 12g of oxygen gas = 0.375 mole (b) 18 gm of water means = 1 mole 20 gm of water means \(\frac{20}{18}\) mole = 1.11 mole (c) 22 g of carbon dioxide means \(\frac{22}{44}\) = 0.5 mole.

Convert into mole:(a) 12 g of oxygen gas(b) 20 g of water(c) 22 g of carbon dioxide

Answer»

(a) 32gm of oxygen means 1 mole

12gm oxygen means \(\frac{12}{32}\) mole

∴ 12g of oxygen gas = 0.375 mole

(b) 18 gm of water means = 1 mole

20 gm of water means \(\frac{20}{18}\) mole = 1.11 mole

\(\frac{22}{44}\) = 0.5 mole.
