Answer:
61.39%
Explanation:
The percent yield of a substance can be calculated using the formula:
Percent yield = actual yield/theoretical yield × 100%
Based on the information provided on the reaction in this question, the theoretical yield is given as 99.2g while the actual yield is given as 60.9g.
Hence, the percent yield is calculated thus:
% yield = 60.9/99.2 × 100
% yield = 0.6139 × 100
% yield = 61.39%
The percent yield is 61.39%
The answer is car a is moving faster than car b
