Question

The density of pure silver is 10.5 g/cm3 at 20 °C. If 6.77 g of pure silver pellets is added to a graduated cylinder containing 15.5 mL of water, to what volume level will the water in the cylinder rise?

Answer 1

The density of pure silver is 10.5 g/cm3 at 20 °C. If 6.77 g of pure silver pellets is added to a graduated cylinder containing 15.5 mL of water, to what volume level will the water in the cylinder rise?

Facts:

10.5 g silver = 1 ml silver

6.77 g silver X 1 ml silver

___________________________    = 0.644 ml silver

                        10.5 g silver

The volume of silver is 0.64 ml. when placed in the graduate cylinder, this is the amount of volume the silver will displace. The final volume level will be: 16.1ml

Answer 2

set up a ratio: 6.77g/xcm3= 10.5 g/1cm3

solve for x: x= 0.644cm3

1ml=1cm3

final volume= 15.5 + 0.64=16.14ml
