Question

At the beginning of a science experiment, Betty had 40 milliliters of solution. During the experiment, the change in the volume of the solution was – 11 milliliters. What is the final volume of the solution? milliliters

Answer 1

`Final\ Volume = 29ml`

Explanation:

Given

`Initial\ Solution = 40ml`

`Change = -11ml`

Required:

Determine the final volume of the solution

The final volume is calculated as thus:

`Final\ Volume = Initial\ Volume + Change`

Substitute values for Initial Volume and Change.

This gives

`Final\ Volume = 40ml - 11ml`

Subtract 11 from 40

`Final\ Volume = 29ml`

Hence, Betty had 29 ml of the solution
