Question

What is the mass of exactly 1 mole of each of the compounds? n2o5 : 108.0 g fe(clo)2 : 158.7 g fe(clo3)2 :

Answer 1

The mass of N2O5 is 108.0 g

The mass of Fe(ClO)2 is 158.7 g

The mass of Fe(ClO3)2 is 222.7 g

Step-by-step explanation:

Use this formula to calculate the mass of a compound:

number of moles=
`(mass)/(molar mass of compound)` or in shorter form: n=
`(m)/(M)`.

Since you're given the number of moles and the molar mass of each compound, simply plug those values into the formula above and solve for the mass (mass=number of moles x molar mass of compound).

Sample calculation for the mass of N2O5:

Molar mass=108.0 g/mol

Number of moles=1 mol.

Mass=?

Mass=number of moles x molar mass of compound

Mass=1 mol. x 108.0 g/mol.

Mass=108.0 g
