Question

PLEASE HELP:

A marble, or small sphere, made of stone is found to have a mass of 3.05 grams. To find its volume it is placed in a graduated cylinder that originally contains 10.00 mL of water. When the marble is placed in the graduated cylinder, the new volume of the water and marble together is 11.20 mL. o Calculate the volume of the marble (Be sure to include units). o Calculate the density of the marble (Be sure to include units).

Answer 1

The marble's volume is equal to 1.2 $cm^{3}$
Density= mass/volume
Mass= 3.05 Grams
Volume= 1.2 cm^3
3.05/1.2= 2.92 g/mL
