What is the molar mass of copper(l) nitrate, #Cu(NO_3)_2#?

Here's a tip before we get started:

To start, make sure you have your handy periodic table handy so you can figure out what Cu, N, and O's atomic weights are.

Cu weighs 63.55 g/mol, N weighs 14.01 g/mol, and O weighs 16.00 g/mol in atomic weight.

We have 1 atom of Cu, which has an atomic weight of 63.55 g/mol according to the chemical formula.

The next atom is one N atom, which has an atomic mass of 14.01 g/mol.

Since you have three O atoms, we would multiply the O atomic mass by three to get 48.00 g/mol.

To find the molecular weight of the entire compound, you now need to add the masses of all the individual atoms:

125.55 g/mol is equal to 63.55 g/mol plus 14.01 g/mol plus 48.00 g/mol.

The molar mass of copper(I) nitrate, Cu(NO₃)₂, can be calculated by adding the atomic masses of each element in the compound:

Copper (Cu) has an atomic mass of approximately 63.55 g/mol. Nitrogen (N) has an atomic mass of approximately 14.01 g/mol. Oxygen (O) has an atomic mass of approximately 16.00 g/mol. There are two nitrate ions (NO₃) in the compound, so we need to multiply the atomic mass of nitrogen and oxygen by 3 for each nitrate ion.

Molar mass = (1 x atomic mass of Cu) + (2 x (atomic mass of N + 3 x atomic mass of O))

Molar mass = (1 x 63.55) + (2 x (14.01 + 3 x 16.00)) Molar mass = 63.55 + 2 x (14.01 + 48.00) Molar mass = 63.55 + 2 x 62.01 Molar mass = 63.55 + 124.02 Molar mass = 187.57 g/mol

So, the molar mass of copper(I) nitrate, Cu(NO₃)₂, is approximately 187.57 g/mol.
