Golf ball has less mass than a tennis ball because it
2 answers:
Explanation:
Since, density is the amount of mass present in volume of the substance.
Hence, Density =
So, more is the mass of a substance more will be its density. Whereas more is the volume occupied by a substance less will be its density.
This also means that when more matter is present within a substance then it will have more mass. As a result, the substance will have more density.
Thus, we can conclude that golf ball has less mass than a tennis ball because it contains less matter.

Answer: 1. moles
2. 90 mg
Explanation:
According to stoichiometry:
1 mole of ozone is removed by 2 moles of sodium iodide.
Thus moles of ozone is removed by =
moles of sodium iodide.
Thus moles of sodium iodide are needed to remove
moles of
2.
According to stoichiometry:
1 mole of ozone is removed by 2 moles of sodium iodide.
Thus 0.0003 moles of ozone is removed by = moles of sodium iodide.
Mass of sodium iodide= (1g=1000mg)
Thus 90 mg of sodium iodide are needed to remove 13.31 mg of .
