In the following question, a statement of assertion is followed by a statement of reason. Mark the correct choice. Assertion : 1 mole of water is equal to 6.023xx10^(23) molecules. Reason : The mass of one mole of a substance in grams is called the molar mass.

3.6xx10^(22)NH_(3) molecules contain how many moles of hydrogen?

What is the mass of 0.5 mole of ozone molecule?

The term mole first used by Ostwald in 1896 refers for the ratio of mass of a substance in g and its molecular weight. 1 "mole" of a gaseous compound occupies 22.4 "litre" at NTP and contains 6.023xx10^(23) molecules of gas. weight of 1 "atom" of hydrogen is:
