How do the mathematical relationships you figured out about the effects of mass and speed of an object on its kinetic energy help you make more-accurate predictions for whether a collision would produce damage in some cases and not others?

There are 0.54 moles of sodium carbonate are contained by  57.3 grams of sodium carbonate.

we can calculate number of moles in a compound by dividing number of grams of compound by the molar mass of the compound.
molar mass of sodium carbonate = 105.987 g/mol
now, 57.3 / 105.987 = 0.54 moles
