What is the molar mass of copper(l) nitrate, #Cu(NO_3)_2#?
1 Answer
The molar mass of
Explanation:
Based on the formula you've given me, that compound would actually be copper (II) nitrate. Copper (I) nitrate is
Before we begin here's a tip:
atomic weight of element
First, you want to have your handy dandy periodic table available so you can determine the atomic weight of Cu, N, O
Cu has an atomic weight of 63.55 g/mol
N has an atomic weight of 14.01 g/mol
O has an atomic wight of 16.00 g/mol
Based on the chemical formula, we have 1 atom of Cu, which would have an atomic weight of 63.55 g/mol
Next, we have 1 atoms of N, and that has an atomic mass of 14.01 g/mol
You have 3 atoms of O so we would multiply the atomic mass of O by 3 to obtain 48.00 g/mol.
Now you want to add the mass of each atom together to obtain the molecular weight of the entire compound:
63.55 g/mol + 14.01 g/mol + 48.00 g/mol = 125.55 g/mol
