The mass of 0.0130 moles of an acid is 1.051 g. What is the molar mass of the acid?

A. 0.0124 g/mol
B. 150. g/mol
C. 80.9 g/mol
D. 98.2 g/mol

Answer :

Final answer:

The molar mass of the acid is approximately 80.9 g/mol.


Explanation:

The molar mass of an acid can be calculated using the formula: Molar mass (g/mol) = Mass (g) / Amount of substance (mol). In this case, the mass of the acid is given as 1.051 g and the amount of substance is given as 0.0130 moles. So, the molar mass of the acid is: 1.051 g / 0.0130 mol = 80.923 g/mol. Rounding to the nearest decimal place, the molar mass of the acid is approximately 80.9 g/mol.
