An empty beaker weighs 32.4257 g. A 10-mL pipet sample of an unknown liquid is transferred to the beaker. The beaker weighs 40.1825 g when weighed with the liquid in it. Calculate the density of the unknown liquid.
omg that first answer was weird.
 
Hi

The formula for density is: d = m/v. Density can be measured in kilograms per cubic meter or grams per cubic centimeter, but in this case it is in grams per cubic centimeter (ml).

So firstly we must get the mass of the unknown liquid;
40.1825 - 32.4257 which equals to 7.7568
now we put the numbers in the equation;
d = ? m = 7.7568 (in grams) v = 10 (in ml)
d = 7.7568/10 therefore density (d) for this liquid is 0.77568 g/ml
