A measured mass of an unreactive metal was dropped into a small graduated cylinder half filled with water. The following measurement were made: Mass of metal =25.200g Volume of water before addition of metal =12.5mL Volume of water after addition of metal =15.0mL The density of the metal should be reported as:
10.0800g/mL
10.1g/mL
10.080g/mL
10.08g/mL
A
10.08g/mL
B
