So however again, we discover ourselves doing math as soon as we thought the course was chemistry! because that this we"re walking to do a standard conversion that we execute a many in GenChem, converting from grams come moles.

You are watching: How many moles of n are in 0.197 g of n2o?

In this case, we"re beginning with 0.205g N2O. Let"s walk ahead and also convert the to moles by making use of 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 obtained to moles of dinitrogen monoxide - now we require to understand how many moles the nitrogen! We see that there"s a subscript of 2 after ~ the N, an interpretation there space two mole of N because that every mol the N2O. You deserve to think of that in terms of food -- because that every 1 sandwich, there space two pieces of bread.

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

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

Hope the helps :)
