please rate my answer and feel free to ask if you have any doubt

3.129 44.01 Port A) mass of unknown compound = 1. Goog 3.129 g of CO₂ , 1.700 g of no moles of co₂ = 3.12 2 = 0.0718 males of CO₂ moles of 10 = 1.701 = 1 og me 18000 o 0944 30 na piuided bymin 0.0711 mile of c I make of c 3 mal ofc Got mode c » Cang D. 1988 male of h 2.60 mloft 8 mal of c . so the correct option is (d) C34602 Porta 5.29 g of c, 0.962 g of h, 3.52g of o male of C = - 5.299 - 0.43962 0 12.01 yima 0.8676 = 910 make of 879.96 - до% 9г- 1 1 mole yo = 3.5.2002 0.22 Answer (d) C2h40
