Calculate the number of Mole in 205g of nitrogen |
|
Answer» Answer: In this case, we're starting with 0.205g N2O. Let's go ahead and convert that to moles 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 moles of dinitrogen monoxide - now we need to know how many moles of nitrogen! We see that there's a subscript of 2 after the N, meaning there are two moles of N for every mol of N2O. You can think of it in terms of food -- for every 1 sandwich, there are two pieces of bread. So let's multiply the NUMBER of moles of N2O by 2, to GET moles of N! .00466 mol N2O * ( 2 mol N / 1 mol N2O) = .00932 mol N!
