Question

convert into moles (a) 12g of oxygen gas (b)0.5mole of water molecules ​

Answer 1

Answer:

(a) 32 g of oxygen gas = 1 mole

Then, 12 g of oxygen gas = 12 / 32 mole = 0.375 mole

(b) 18 g of water = 1 mole

Then, 20 g of water = 20 / 18 mole = 1.111 mole

(c) 44 g of carbon dioxide = 1 mole

Then, 22 g of carbon dioxide = 22 / 44 mole = 0.5 mole

Answer 2

Answer:

(a) 32 g of oxygen gas = 1 mole

Then, 12 g of oxygen gas = 12 / 32 mole = 0.375 mole

(b) 18 g of water = 1 mole

Then, 20 g of water = 20 / 18 mole = 1.111 mole

(c) 44 g of carbon dioxide = 1 mole

Then, 22 g of carbon dioxide = 22 / 44 mole = 0.5 mole
