"The density of pure silver is 105 g/cm³ at 20°C. If 5.25 g of pure silver pellets is added to a graduated cylinder containing 11.2 mL of water, to what volume level will the water in the cylinder rise? [1 mL = 1 cm³]"
Can someone help me by EXPLAINING how one would come to their answer? Thanks so much! :D

I seem to have made a typo. It's not supposed to be 105 g/cm cubed, but 10.5 g/cm^3:
The density of pure silver is 10.5 g/cm³ at 20°C. If 5.25 g of pure silver pellets is added to a graduated cylinder containing 11.2 mL of water, to what volume level will the water in the cylinder rise? [1 mL = 1 cm³]

5.25g of silver, in terms of volume is (5.25g)/(105g/cm3) = 0.05 cm3 volume of silver is present. Since its a solid and does not mix with the water, the volume should be additive, so the volume should increase by 0.05mL

The key to your answer lies in the fact that 1mL = 1cm^3. This means that there are 105g of silver pellets in 1mL of silver pellets. Since you are only adding 5.25g silver pellets, you are adding (5.25/105)mL silver pellets to the graduated cylinder. Thus you are adding 0.05mL to the cylinder. Final volume is 11.25mL.

density=wieght/volume, the volume of (5.25 g silver pellets) is 5.25 / 10.5 = 0.5 cm3 , so the volume of the water in the cylinder will be 11.25 ml.

ok, so the density is 105...that means that the mass (5.25 g pure silver) times volume (11.2 mL of water). you add the density to the mL of water, and I believe you have your answer...If I'm wrong, check with me later.

well i would think that 105g of silver equals a CM cubed. So 5.25/105= .05 CM cubed. if 1mL = 1CM cubed then .05CM cubed = .05mL so 11.25mL is the answer. im just guessing tho

ok so now the answer would be 5.25/10.5=.5. so it would be 11.25+.5= 11.75mL


is this how u do ur homework?

5.25 g of pure silver would occupy 0.5 cm^3, or 0.5 ml, given a density of 10.5 g/cm^3.

Add 0.5 ml to your original volume of 11.2 ml, and you'll get 11.7 ml.
