Given that the mass of an oxygen atom is 16 amu and that of a hydrogen atom is 1 amu,1 mole of water would be equal to A)17 amu. B)18 amu. C)15 grams. D)18 grams. E)6.02 *10²³grams.

Question

Quizplus · Accepted Answer

The molecular formula of water is H2O, which consists of two hydrogen atoms and one oxygen atom. The total mass of one mole (6.02 x 10^23 molecules) of water can be calculated as follows:

2 x (1 amu) (for the two hydrogen atoms) + 1 x (16 amu) (for the one oxygen atom) = 18 amu

Therefore, the mass of one mole of water is 18 grams.
