So,18.01528 g/mol is the molecular mass of water. 0 Reply Share Share Share on Facebook Share on Twitter Share on LinkedIn Share on WhatsApp Abhinav.arjun47 Moradabad, India 1k Questions 2k Answers 14 Best Answers 4k Points View Profile Abhinav.arjun47 Added an answer on May 9, 2020 at 8:23 am 18.01534 grams/mole. 0 Reply Share Share Share on Facebook Share on Twitter Share on LinkedIn Share on WhatsApp Charu New Delhi, 602 Questions 2k Answers 4 Best Answers 2k Points View Profile Charu Added an answer on May 8, 2020 at 9:53 am Hence water has 2 hydrogen atoms and one oxygen atom. The atomic weight of hydrogen is 1.00797 and for oxygen the atomic weight is 15.9994. So the molar mass of H2O is 15.9994 + (2 x 1.00797) which equals 18.01534 grams/mole. 0 Reply Share Share Share on Facebook Share on Twitter Share on LinkedIn Share on WhatsApp Leave an answerLeave an answerCancel reply Featured image Select file Browse Save my name, email, and website in this browser for the next time I comment.
