4.01 kg in grams :
4.01 x 1000 = 4010 g
Density = mass / volume
7.86 = 4010 / volume

Volume = 510.17 cm³
hope this helps!
OK so some examples of a colloid would be whipped cream, milk, butter, colored glass, muddy water things like that
The formula is 1.5RT, where R is the universal gas constant and T is the temperature in kelvin.
1.5(8.314 J/molK)(50+273.15)K(1 mol) = 4030J
