the molar mass of CopperII Nitrate

CU(NO3)2 is _________grams

Ok so I
1. Cu= 63.55
2. N=14.01
3. 0= 6 X 16.00=96

I get 96.+14.01+63.55? =173.56
Answer is 188 grams? What did I do wrong?
Thank You

I got it myself:

Yeah!

63.55 + (14.01 + 48)x 2 = 187.55g/moles

187.55g/moles

To find the molar mass of Copper(II) Nitrate (Cu(NO3)2), you need to correctly calculate the atomic masses of each element and then add them together.

Here are the correct atomic masses for the elements:
- Cu (Copper) = 63.55 g/mol
- N (Nitrogen) = 14.01 g/mol
- O (Oxygen) = 16.00 g/mol

Now, let's calculate the molar mass:
1. Start with the Cu atom: 1 * 63.55 g/mol = 63.55 g/mol
2. Move to the N atom: 2 * 14.01 g/mol = 28.02 g/mol
3. Finally, the O atoms: 6 * 16.00 g/mol = 96.00 g/mol

Now, add up all the values:
63.55 g/mol + 28.02 g/mol + 96.00 g/mol = 187.57 g/mol

Therefore, the correct molar mass of Copper(II) Nitrate is approximately 187.57 grams per mole, not 188 grams.
