ok..heres another question..its kinda related to math..
A solid has a mass of 83 grams. A graduated
cylinder contains 33 mL of water. When the
solid is completely submerged in the water,
the new water level reads 60 mL.
What is the density of the solid?

A solid has a mass of 83 grams. A graduated cylinder contains 33 mL of water. When the solid is completely submerged in the water, the new water level reads 60 mL. What is the density of the solid?
density = mass/volume
mass of solid = 83 grams
volume of solid = 60-33=27mL
density = 83/27=3.07g/mL
convert your units according to the question
1 ml = 1.0 × 10-6 cubic meters

- because the divisor has 3 sig digits.

heres one more question:
A pint of blood would be how many mL? (1 L
= 1.057 qt and 1 qt = 2 pints.)
1. 454 mL
2. 946 mL
3. 473 mL
4. 529 mL

1qt = 2pints...so 1 pint = 0.5 qt
1L = 1.057 qt...so 0.5qt = 0.473L
0.473L = 473mL.
