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

• Chemistry -

I got it myself:
Yeah!

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

• Chemistry -

187.55g/moles
