So yet again, we discover ourselves doing math once we assumed the course was chemistry! for this we"re walk to perform a traditional conversion that we perform a lot in GenChem, converting from grams come moles.

You are watching: How many moles of n are in 0.207 g of n2o?

In this case, we"re beginning with 0.205g N2O. Let"s go ahead and convert that to mole by using the molar mass, which is 44.013 g/mol.

.205 g N2O * (1 mol N2O / 44.013 g N2O) = 0.00466 mol N2O

So we got to mole of dinitrogen monoxide - currently we need to understand how plenty of moles of nitrogen! We see that there"s a subscript of 2 after ~ the N, an interpretation there space two mole of N for every mol that N2O. You have the right to think of that in terms of food -- for every 1 sandwich, there are two piece of bread.

So let"s multiply the variety of moles of N2O by 2, to acquire moles the N!

.00466 mol N2O * ( 2 mol N / 1 mol N2O) = .00932 mol N!

Hope that helps :)
