Question

what is the molar mass of the element
a 1.008
b 15
c 1
d 30.974

Explanation:

Step1: Recall molar masses of elements

Hydrogen (H) has a molar mass of approximately 1.008 g/mol. The options: 1.008 (option a) matches H's molar mass. 15, 1, 30.974 (P's molar mass) don't fit common simple element molar masses here.

Step2: Identify the correct option

Among the choices, 1.008 is the molar mass of hydrogen, so option a is correct.

Answer:

a. 1.008
