Question 78

A 1.45 g sample of liquid propanone (C3H6O\text{C}_3\text{H}_6\text{O}C3​H6​O, Mr=58.0M_r = 58.0Mr​=58.0) is burned completely in oxygen.

C3H6O(l)+4O2(g)→3CO2(g)+3H2O(l) \text{C}_3\text{H}_6\text{O(l)} + 4\text{O}_2\text{(g)} \rightarrow 3\text{CO}_2\text{(g)} + 3\text{H}_2\text{O(l)} C3​H6​O(l)+4O2​(g)→3CO2​(g)+3H2​O(l)
