Answer:

Percent error = 8.3%

Explanation:

Given data:

Accepted value of specific gravity = 7.2

Measured value of specific gravity =  7.8

Percent error = ?

Solution:

Percent error = measured value - accepted value / accepted value × 100

Now we will put the values in formula.

Percent error = 7.8 - 7.2/7.2 × 100

Percent error = 0.6/7.2 × 100

Percent error = 0.083 × 100

Percent error = 8.3%
