Answer to Question #230432 in General Chemistry for Vee

Question

You have a 100.0 mL graduated cylinder containing 50.0 mL of water. You carefully place 123 g piece of brass (density= 8.56 g/mL) into the water. What is the final volume reading in the graduated cylinder?

Answer 1

mass = volume x density

123g = volume x 8.56g/mL

V = ?

$Volume=\frac{123g}{8.56g/mL}$

Volume =14.4mL

The brass will displace its volume so the water will rise from 50.0 mL to 50.0mL+ V.

50.0mL+14.4mL=64.4mL

Final volume reading in the graduated cylinder=64.4mL
