If 225 mL of water at 25°C is frozen at 0.0°C, what volume of ice is created? (Density of water at 25°C = 0.997 g/mL; density of ice at 0.0°C = 0.917 g/mL)
If 225 mL of water at 25°C is frozen at 0.0°C, what volume of ice is created? (Density of water at 25°C = 0.997 g/mL; density of ice at 0.0°C = 0.917 g/mL).
Density=Mass / Volume
.997 =Mass/225
Mass=225 x .997
Mass=224.325g- mass of 225 ml od water, which would be the mass of the ice.
.917 =224.325 / Volume
Volume=224.325 / .917
Volume=244.629 ml or cm^3-volume of the formed ice.
+37155 If you multiply VOLUME (ml) x DENSITY (g/ml) , you will get g
So....how many grams of water @ 25 degrees do you start with?
225 ml x .997 g/ml = 224.325 g
When it FREEZES it will be the same number of g BUT it will occupy a bigger VOLUME because the DENSITY of ICE is LESS (This is why ice floats in water)
IF you DIVIDE g by VOLUME (ml) you get DENSITY g/ml
For THIS ice 224.325 g/ ? ml = .917 g /ml solve for ? = 244.629 ml (which explains why your soda bottle burst when you placed it in the freezer!
+37155 EVENTUALLY, you may be able to realize that the answer would just be 225 x (.997/.917) = 244.629 ml
without having to go through all fo the other calcs !
