Question

कन्वर्ट इनटू मोले 12 ग्राम आफ ऑक्सीजन 20 ग्राम ऑफ वाटर ​

Answer 1

Answer:

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

Thus, 12 g of oxygen= 321 ×12=0.375 moles

(b) Molecular weight of water (H 2 O) in grams= 2+ 16=18 g=one mole of water

Thus, 20 g of water= 181 ×20=1.111 moles
