The density of pure copper is 8.96 at 20°C. If 5.00 g of pure copper pellets is added to a graduated cylinder containing 14.6 mL

Triss [41]

Answer:

15.2 mL

Explanation:

First we calculate the volume of the copper

$volume = \frac{mass}{density}= \frac{5.00 g}{8.96 g/mL} = 0.5580 mL\\$

when this volume of copper is added to the water, the water level will rise by the level of the volume of copper. So the final volume is:

14.6 mL + 0.5580 mL = 15.158 mL

Since the measuring cylinder is graduated to one decimal place , we can round this up to 15.2 mL
