<em><u>Element: A substance that is made up of only one type of atom. Compound: A substance that is made up of more than one type of atom bonded together. Mixture: A combination of two or more elements or compounds which have not reacted to bond together; each part in the mixture retains its own properties.</u></em>

There are 618.68 g in 4.5 moles of NaF.
The total number of moles of any substance equals the ratio of its given mass in a chemical reaction to the mass of one mole or molar mass of that substance.
It is known that one mole of NaF or molar mass of NaF is 41.98 g/mol.
Given that number of moles is 4.5 moles.
Therefore, calculate the mass of NaF in grams as follows.
No. of moles = Given mass / Molar mass
mass in grams = No. of moles × Molar mass
= 4.5moles × 41.98 g/mol
= 188.91 g
Hence, we can conclude that there are 188.91 g in 4.5 moles of NaF.

Answer: M = 0.01 M C12H22O16
Explanation: First convert the mass of C12H22O16 into moles using the molar mass of the compound.
5 g C12H22O16 x 1 mole C12H22O16 / 342 g C12H22O16
= 0.01 mole C12H22O16
To calculate the molarity we will use the following formula.
M = n / L
= 0.01 mole / 1 L
= 0.01 M C12H22O16
