Answer: The data are consistent with the law of conservation of mass because the mass of reactants equals the mass of products
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
Given: mass of sodium = 12.8 g
mass of chlorine = 19.6 g
mass of reactants = mass of sodium + mass of chlorine = 12.8 g + 19.6 g = 32.4 g
Mass of product = Mass of sodium chloride = 32.4 g
As mass of reactant = mass of products
, Thus results are in accordance with the law of conservation of mass.
Density equals Mass/Volume. The equation for this problem would be 1.62 kg/205 mL. If it’s easier, this can be converted to 1620 g/205 mL. The answer would be 7.902 (rounded to the nearest thousandth). Good luck!
