CALCULATE IT YOURSELF!
a)How many moles of what?Incomplete question.....
But If youre talking about HNO3 I THINK it is...
{4.0 X 10 (24th power)}/{6.02X10 (23th power)}
b) {(The mole of HNO3) / 2} X 18
I'm not good at chemistry so that their is a very high probability that I'm wrong............at least that what I always do........
