Will a block of material having a volume of 1.97 x 105 cm3 and weighing 1.59 kg float or sink when placed in water? Show calculations to support you answer.

float

Explanation:

density= mass/ volume (kg/m^3)

1.59 kg/0.197 m^3

=8.07 kg/m^3

density of H2O= 1000 kg/m3

since density(block)<density(H2O), the block will float

(can also be done in g/cm^3)

1590 g/ (1.97*10^5 cm3)= 0.00807 g/cm^3 < 1 g/cm^3 (h2O)

the law of conservation of mass states that in a chemical reaction, the total mass of reactants is equal to the total mass of products. because atoms are only rearranged in a chemical reaction, there must be the same number of sodium atoms and chlorine atoms in both the reactants and products
