I can do part a but I'm not sure where to begin for parts b and c. I usually have trouble when dealing with mixing problems like these.

i remember doing this question last term lol, it was pretty confusing at first for me haha, mixing problems are the worst for me too lol
so for part a, you should have gotten 2w grams/min i think. for part b: if there are 1000L of pure water in the tank and Q grams of salt at one particular moment in time, and you are trying to find how much salt in 1L, you divide Q by 1000 as you're looking for 1L only.

for part c, you account for the outflow of salt and water (at the same rate as part a), using the answer you got in part b - you should get Qw/1000
