Question
See the example in Introduction for set-up of calculations. Calculate the number of (a) moles of N, and (b) atoms of N in 12.7 g of nitrogen gas, N2. You do not need to include units in your answer, as they have already been included below, and use MM of N2 = 28.0134 g/mol. Type your answers in as an exponential expression (e.g. 1.23E-2 instead of 0.0123), where appropirate, and round your answers to three significant figures. moles
