CH and O is the reactants while CO and H2O is the products
The statement that best explains why heating a liquid affects its viscosity is that "The molecules move faster at higher temperatures and overcome attractions more easily."<span>. Remember that viscosity is a physical property of the fluids that measure the resistance (opposition) to flow and it, generally decreases, as the temperature increases and the intermolecular force decrease.</span>
Density is defined as the ratio of mass and volume. The formula of density is:
-(1)
Density of milk = 
(given)
Volume of milk = 
(given)
Substituting the values in formula (1):
Hence, the mass of the milk is 
.
