0.10 mole of C4H10O reacts completely with molecular oxygen, O2. The number of mole of oxygen molecules used is A. 0.50 B. 0.55 C. 0.60 D. 0.65
Worked Solution & Example Answer:0.10 mole of C4H10O reacts completely with molecular oxygen, O2 - VCE - SSCE Chemistry - Question 5 - 2005 - Paper 1
Step 1
Calculate the moles of oxygen required
Answer
To determine the number of moles of oxygen, we first refer to the balanced chemical reaction for the combustion of C4H10O:
From the balanced equation, we see that 1 mole of C4H10O reacts with 6 moles of O2. Given that we have 0.10 moles of C4H10O, we can calculate the required moles of O2:
Therefore, the number of moles of oxygen molecules used is 0.60.
