Question

Molar Mass of:
CaCl2 * 2H20

I got the answer 129

Answer 1

So CaCl2 is 110.98
2H2O is 36.04
Assuming ur * is a +
Then 110.98+36.04=147.02
So ur answer was not right

Answer 2

okay, because I was told that you do not count coefficients when finding molar mass

Answer 3

Wait, let me check something really quickly. U might be right then

Answer 4

Nvm. I think I'm right. I don't know why your teacher told you to ignore the coefficients, because it doesn't really make sense, because u are trying to calculate 2 moles of H20+ 1 mole of CaCl2. If u ignore the coefficient, u would only be finding one mole of H20

Answer 5

Alright. Thanks

Answer 6

No problem.
