Branch of Hydraulics that studies fluids at rest?
(a)
Quantity of mass per unit volume of a material substance
(a)
International units for density
m3kg
Lkg
cm3g
mkg
A river stone with a mass of 7kg displaces 2.5 L of water when placed in a large overflow container. What is the density of the stone? (a) kg/L
NOTE: The volume displaced would be the same as the stone's.
Round your answer to the nearest tenth, e.g. 5.2 kg/L
While maxing soap. A person combines 2 liters of Glycerin (1259 kg/m3) and 0.5 liters of Cocoa butter (974 kg/m3). How much does this mixture weight? (a) kg
NOTE: Densities are provided in the parenthesis ( 000 kg/m3)
Round your answer to the nearest whole number
1 m3 = 1000 L
