Complicated chemistry Density problems. Help me!
I don't know how to do these. Could you show me how?
A 10.0 mL sample of acetone is pipetted into a flask with stopper. The mass is found by difference to be 7.899 g. Calculate the density of the liquid.
A piece of chalk weighing 15.600 g displaces 6.5 mL of water in a graduated cylinder. Calculate the density of the chalk.
A rectangular block of jade has a mass of 146.25 g and measures 10.00 cm by 3.00 cm by 1.50. What is the density of the jade?
Find the thickness of a piece of gold foil which has a mass of 1.000 g and measures 5.00 cm by 10.00 cm. The density of gold is 18.9/cm^3.
I got some answers. I need to study off of these though. I don't know how.. I have to know this by tomorrow.
