Question

HELP ASAP!!

You have a 100.0-mL graduated cylinder containing 50.0 mL of water. You carefully place a 109-g piece of brass (density = 8.56 g/mL) into the water. What is the final volume reading in the graduated cylinder?


SHOW WORK PLEASE!!!

Answer 1

109/8.56=12.7
50+12.7
V=62.7

Mass= Volume x Density so i divided the mass and density to get the volume. and afterwards i would just add it to the mass to get my final answer

Answer 2

The final volume reading in the graduated cylinder 62.7 ml.

Step-by-step explanation:

Initial level of the water in graduated cylinder = 50 .0 ml

To calculate volume of a substance, we use the equation:

`\text{Density of substance}=\frac{\text{Mass of substance}}{\text{Volume of substance}}`

We are given:

Density of liquid = 8.56 g/mL

Mass of substance = 109 g

Putting values in above equation, we get:

`8.56 g/mL=\frac{109 g}{\text{Volume of substance}}\\\\\text{Volume of substance}=12.7 mL`

Volume occupied by the substance = 12.7 mL

Volume occupied by the substance will increase the volume of the water more by 12.7 ml.

The final volume reading in the graduated cylinder :

50 ml + 12.7 mL = 62.7 mL
