Question

What is the mass, in grams, of 1.000 mole of each of the following substances?

a)S (sulfur)
b)Mg (magnesium)
c)NH₃ (ammonia)
d)H₂SO₄ (sulfuric acid)

Answer 1

The molar mass refers to the mass of one mole of a substance. The molar mass of S is 32.06 g/mol, Mg is 24.31 g/mol, NH₃ is 17.03 g/mol, and H₂SO₄ is 98.09 g/mol.

Step-by-step explanation:

The molar mass of a substance is the mass of one mole of that substance. To calculate the molar mass, you need to sum up the atomic masses of all the atoms in the molecule.

a) The molar mass of S (sulfur) is 32.06 grams per mole.

b) The molar mass of Mg (magnesium) is 24.31 grams per mole.

c) The molar mass of NH₃ (ammonia) is 17.03 grams per mole.

d) The molar mass of H₂SO₄ (sulfuric acid) is 98.09 grams per mole.
