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.
