What is the molar mass of hydrogen?
A. 1.01 g/mol
B. 11.01 g/mol
C. 101.1 g/mol
D. .0111 g/mol
D
I don't think so. How did you arrive at that number?
meant A
How did you arrive at that number? Or did you guess?
guessed
I don't think the right answer is there if you posted the question and choices correctly. The atomic mass of hydrogen (H) is 1.01 but the molar mass of hydrogen (H2) is 1.01 x 2 = 2.02.
To find the molar mass of an element, you need to refer to the periodic table. The molar mass is equal to the atomic mass of the element expressed in grams per mole. Hydrogen, with symbol H, has an atomic mass of approximately 1.01 amu (atomic mass units).
To convert atomic mass to molar mass, you simply express it in grams per mole. Therefore, the molar mass of hydrogen is 1.01 g/mol.
So, the correct answer is A. 1.01 g/mol.
