Li: atomic mass 6.941
F: atomic mass 18.998
Lithium fluoride is made up of these two elements. Its balanced formula is LiF (Li+1F-1). Adding both its atomic masses equals 25.939. Therefore one mole of LiF is equal to 25.939 grams. So, 1.5 moles of LiF is equal to 38.90 grams.
It is because the molar mass of LiF is 25 g/mol. Therefore, 1.5 moles of LiF would be equal to 1.5 moles x 25 g/mol = 37.5 grams of LiF. The value may be rounded to 39 grams for simplicity.
39.5 grams Li (1 mole Li/6.941 grams)(6.022 X 10^23/1 mole Li)
= 3.43 X 10^24 atoms of lithium

How many grams of O2 are in 15 moles of O2. with work shown?
To find the grams of O2 in 15 moles, we use the molar mass of O2, which is 32 g/mol. 15 moles x 32 g/mol = 480 grams of O2. Therefore, there are 480 grams of O2 in 15 moles of O2.
How many moles of atom is contained in 15 gram of zinc?
To find the number of moles of zinc in 15 grams, divide the given mass by the molar mass of zinc. The molar mass of zinc is approximately 65.38 g/mol. Therefore, 15 grams of zinc is equal to 0.23 moles of zinc.
How many moles in 15 grams if lithium?
From the periodic table, lithium has an atomic weight of 6.941. The molar mass of an element is the atomic weight in grams. Therefore, 1 mole Li = 6.941g Li Therefore, moles Li = 15g Li X 1 mole Li/6.941g Li = 2.2 moles Li
How many molecules of ethane gas C2H6 are in 15 grams of the compound?
To calculate the number of molecules in 15 grams of ethane (C2H6), first find the molar mass of C2H6, which is 30.07 g/mol. Next, calculate the number of moles in 15 grams using the formula: moles = mass / molar mass. Finally, use Avogadro's number (6.022 x 10^23 molecules/mol) to convert moles to molecules.
