Question

1. Marisa determined the melting point of a substance to be 24.5C. Find the percent error of her measurement if the actual melting point is 31.2C.

Answer 1

`\%\ Error = 21.5\%`

Step-by-step explanation:

Given

`Measured = 24.5`

`Actual = 31.2`

Required

Determine the percentage error

First, we need to determine the difference in the measurement

`Difference = |Actual - Measured|`

`Difference = |31.2 - 24.5|`

`Difference = |6.7|`

`Difference = 6.7`

The percentage error is calculated as thus:

`\%\ Error = (Difference * 100\%)/(Actual)`

`\%\ Error = (6.7 * 100\%)/(31.2)`

`\%\ Error = (670\%)/(31.2)`

`\%\ Error = 21.4743589744\%`

`\%\ Error = 21.5\%` approximated
