What number of moles does 32.00 g of LiF represent?
I mole of LiF is (7 + 19) = 26 g. Thus 32 g is 32/26 moles = 1.23 moles.
How many moles of aluminum are present in 856g of aluminum sample?
Moles = Mass/ Relative Molecular Mass Aluminum forms Al2 compounds, so the relative molecular mass is 2 * 13 = 26. 856/26 = 32.9 (3sf)
How many atoms of oxygen are contained in 12.3 kg of carbon dioxide?
12.3 kg=12,300 g 12,300 g/44.01g (molar mass) = 279.5 moles 279.5 moles x (6.02 x 10^23) = 1.68248 x 10^26 x 2 = 3.366 x 10^26 atoms of Oxygen in CO2
How many atoms are there in 250 mol Si?
1 mole of anything is 6.022 x 1023 atoms or molecules of that substance. Thus, 2500 atoms of a substance is about 4.151 x 10-21 moles of that substance.

What is the mass in grams of 3.41x10e26 molecules of water?
first you divide by avagadro's number to get the number of moles. 3.41x10^26 / 6.022x10^23 = 566.25 moles The molecular mass of water is 18. moles is mass/molecular weight so moles by the mass is the weight. 566.25*18 is 10192.63g. This is 10.193kg. Are you sure your molecule count was not exponentially lower?
How many grams are in 0.50 mol H2SO4?
