Exercise 11a Calculations based on concentrations in solution ... The mass of an individual atom is very small and it is much more convenient to measure atomic.

14g

Explanation:

assuming that N2 is a gas, use the gas formula ( mole = volume/24) to find the number of moles

then once you have found the moles (0.5 mol) use the (mole = mass/mr) formula to find the mass

so, 0.5 x 28 = 14g
