Answer to Question #160476 in General Chemistry for princess

Question

If you are given 150 grams of C₄H_{10 ,}How many grams of O₂ would you need to completely react with the C₄H₁₀ ? 

Answer 1

2C₄H₁10g)+13O₂(g)→8CO₂(g)+10H₂O(g).

2 mole of C₄H₁10reacts with 13 O₂

no. of moles in 150g of C₄H₁₀ 150/58 = 2.58 moles

no. of moles of O₂ required = 16.81 moles

mass of O₂ required = 16.81×32

= 537.9 g
