b. 36 g of water

please answer it quickly please please
explain it please​

Answer 1

Answer:

(a) Molecular weight of oxygen in grams = 32 g of oxygen= one mole of oxygen gas

Thus, 12 g of oxygen=  

32

×12=0.375 moles

(b) Molecular weight of water (H

​  

O) in grams= 2+ 16=18 g=one mole of water

Thus, 20 g of water=  

18

×20=1.111 moles

(c) Molecular weight of carbon dioxide (CO
