Question

How many grams are in a mole of hydrogen chloride (hcl)? 1 h 1.01 hydrogen 17 cl 35.45 chlorine a. 1.5 grams/mole b. 35.45 grams/mole c. 36.46 grams/mole d. 72.92 grams/mole

Answer 1

The molecular mass is the sum of the atomic masses of the atoms.

Atomic mass :

H = 1.01 amu

Cl = 35.45 amu

HCl = 1.01 + 35.45

HCl = 36.46 grams/mole

Therefore:

1 mole of HCl is equivalent to 36.46 grams/ mole

answer C
