Question
Mg + 2HCl ➔ MgCl2 + H21.5 g of magnesium takes 4 minutes to react completely. Calculate the mean rate of reaction. Give your answer in g/min.
Solution
To calculate the mean rate of reaction, you need to divide the total amount of magnesium used by the total time taken for the reaction.
Given:
- Total amount of magnesium = 1.5 g
- Total time taken = 4 minutes
Mean rate of reaction = Total amount of magnesium / Total time taken = 1.5 g / 4 min = 0.375 g/min
So, the mean rate of reaction is 0.375 g/min.
