When 5g of a noneelectrolyte is added to 25g of water, the new freezing point is -2.5 C. What is the molecular mass of the unknown compound?
How do I start this problem?
How does these chemical equation balance, step by step? Why do they balance this way?
I already know how they balnace I just don't understand how they balance. why does the O(2*) balance to 25? 2 C(8*)H(18*) + 25 0(2) yields 16 CO(2*) + 18 H(2*)O These ones have me stumped...
