Question

calculate and compare the masses of 0.5 mole of CO and 0.5 mole of N2​

Answer 1

Answer:

hello mate

Molar mass of N2 is 28(since atomic weight of nitrogen is 14and forN2=14*2). So mass of 1 mole of N2 is 28g.Therefore mass of 0.5 mole is 28/2 =14g

follow me

Answer 2

so mass = no of moles * molecular mass i. e for co 0.5*14=7 for n2 0.5* 14 = 7 hence they have same masses. i. e 7 gm.
