Answer:
1. A
2. C
3. B
4. D
5. D
6. B
Explanation:
I'm not quiet sure on 5 but I'm pretty sure its correct
Rearrange the equation n=M÷Mr. Where n = the number of moles. M= the mass in grams. And Mr = the molecular mass of the substance.
Since you are working out mass use the equation M= n x Mr. So you have
6.21 × 111 (molecular mass of CaCl2).
This will give you the answer 689.31 grams which would be your final answer.
