You can view more details on each measurement unit: molecular weight of LiF or grams This compound is also known as Lithium Fluoride. The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles LiF, or 25.9394032 grams.
How many moles are in 39 grams of LiF?
4. The gram formula mass is the sum of the gram atomic masses of the atoms that make up a chemical formula. For lithium fluoride this works out to be 7g + 19g = 26g. Hence the mass of 1 mole of LiF is 26g; and the mass of 1.5 moles of LiF must be 1.5 × 26g = 39g.

- Multiply both the values.
What quantity is equal to one mole of AU?
i) Atomic mass of gold: 196.67 g/atoms, means that 196.97 grams of Au is one mole of Au.
What is the total mass in grams of 0.75 mole so2?
1. 16 g.
How do I calculate moles?
- First you must calculate the number of moles in this solution, by rearranging the equation. No. Moles (mol) = Molarity (M) x Volume (L) = 0.5 x 2. = 1 mol.
- For NaCl, the molar mass is 58.44 g/mol. Now we can use the rearranged equation. Mass (g) = No. Moles (mol) x Molar Mass (g/mol) = 1 x 58.44. = 58.44 g.
