If you re-read what I wrote last night,

grams = moles x molar mass. If I plug in 0.75 for moles and 357.48 for molar mass, I don't get 129.68. As I told you last night, your problem isn't chemistry, it's punching in the right keys on your calculator.

For the second problem you need to go back and read the original instructions.
