4. Suppose that a student performed the experiment and calculations perfectly as directed except that, unknown to the student, the balance was not zeroed but weighed 0.100 g too high throughout the experiment. Would the calculated val- ue for the density of the unknown liquid be correct? That is, would it be equal to, higher than, or lower than the true value.
