Easy
C : 66.07 / 100 x 2.876 = 1.900 g
H : 6.71 / 100 x 2.876 = .1930 g
You get the picture

I think the anser to your question is this:
Mass of C = (66.07/100)*2.876 = 1.90 g
Mass of H = (6.71/100)*2.876 = 0.19 g
Mass of N = (4.06/100)*2.876 = 0.12 g
Mass of O = (23.16/100)*2.876 = 0.67 g
Adding everything up, it adds up to 2.88 g
My answer must be right.Hope this helps :)
