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%
The answer is B.
I think its safe to assume we all have had a cup of ice water. The ice always floats at the surface of the water.
