85.2 gram LiF sample is equivalent to 3,28 moles.
"The amount of grams in one mole a substance" is themolar mass (the mass of 1 mole) of a substance.The molar mass of Lithium oxide (Li2O) is 29.881 g/molThe molar mass of a compound can be calculated by adding the molar masses of the compound's constituent elements.In this case :molar mass of lithium oxide= 2x(molar mass of lithium)+ (molar mass of oxygen)= 2x(6.941) + 15.999=29.881 g/molNotes:* the molar masses of elements are found in the periodic table. * Notice the subscript "2" in the chemical formula of lithium oxide , Li2O. This subscript indicates that two lithium atoms are involved in each lithium oxide atom.Hence, we multiply the molar mass of of lithium by "2" when calculating lithium oxide's molar mass.
85 moles Li x 6.02x10^23 atoms/mole Li = 5.17x10^25 atoms of Li
5 moles of sulfur is equal to 160,3 g.
The answer is 1,668.10-4 moles.
0,25 moles lithium nitride are obtained.
This reaction? 6Li + N2 --> 2Li3N 0.450 moles Li (2 moles Li3N/6 moles Li) = 0.150 moles lithium nitride produced ===========================
0,0864 moles of lithium contain 0,6 g Li.
molar mass of lithium is 6.941 1.9g/6.941=0.273 answer= 0.273 moles
0.0000639mol
Two atoms of lithium, or two moles of lithium.
3 x 0.2 = 0.6 moles
12 moles Li
It is 53M
