Calculate the molar percent of nitrogen in 1kg of Ni(NO2)2.

2. Relevant equations

mol% of A = n(A) / n(total) * 100

3. The attempt at a solution

I'm stuck on this basic question. I have a tendency to say that the molar percent of nitrogen would basically be [tex]\frac{2}{1+2+4} * 100[/tex], basically the nb of moles of N over the sum of the total.

What's causing me confusing is the 1kg.

My question is:if I were looking for the specificnumber of moles, then the mass would be accounted for. But if it'smolar percentt that's wanted, wouldn't it be independent of the mass?

Thanks.

Marc
