Done.
Since density is 1.055g/mL it means it is 1055g/L
Then is simply 46.15/1055 which is then 4.4%

I just did chem 121 last semester. One big mistake I made was not doing the loncapa. It's not essential to do good on tests, but man does it effect your mark if you get lazy with it. My biggest regret is not doing all' the loncapa, I lost almost a whole letter grade because of it. Never again will I make that mistake.
And if you go regularly to tutorials you know 80% of people skip (my guesstimate) .. so the TA's are really willing to help you with loncapa and basically spoonfeed you the answers if you go regularly to tutorial.
Whose your professor?
