Question

what is the molar mass of the element hydrogen - h?

a 1

b 15

c 30.974

d 1.008

Explanation:

The molar mass of hydrogen (H) is approximately 1.008 g/mol. Option a is 1 (a rounded whole number, not the precise molar mass), option b is 15 (incorrect, as 15 is not related to hydrogen's molar mass), option c is 30.974 (which is the molar mass of phosphorus, not hydrogen). So the correct option is d with the value 1.008.

Answer:

d. 1.008
