I solved it. Disreguard the thread
What level of work is this? A-Level?
I don't really know what you mean by A-level. I'm in honors though.
I really don't know where to begin solving these.
Oh, so are you at a university?
Nope. I'm in high school. It's Gen Chem.
I'm not going to do all of these for you because they're pretty straight forward. All you have to do is write out a balanced chemical equation, set up a mole ratio (nx/ny = coefficient x / coefficient y) and solve. Remember n = mass/molarmass for solids n = PV/RT for gases and n = MV for solutions
Could you do one of them as an example? I sort of get what you mean but I'm not completely sure.
