No - strictly speaking the number of moles is the weight/molecular weight
3,56 mol Al is equal to 96,05 grams.
As the periodic table of Elements states, Al has a Molar Mass (Grams/Mole) of 27.0g/mol. So 3 mols of Al mass is the same as 3 times 27.0g/mol. So, the equation is as follows: 3mols x 27.0g/mol = 81.0g. The reason on why it ends with grams is because the unit of moles in 3 will cancel out with the unit of mols in 27.0g.
Molarity= moles/Liters To change grams to moles you divide by the mole weight which is listed on the periodic table. Mol= grams/mol weight The Mole weight of Magnesium Chloride is 59.8 grams/mol Mol=128g/59.8 Mol=2.14 Now, you put the number of moles and Liters into the equation Molarity=2.14 mol/1L Molarity=2.14 So, the molarity is 2.14 M
Molarity = moles of solute/Liters of solution ( 450 ml = 0.450 liters) 5M C6H12O6 = moles C6H12O6/0.450 liters = 2.25 moles C6H12O6 (180.156 grams/1 mole C6H12O6) = 405.351 grams of glucose ( you do significant figures )
One mol is equal to molar mass in grams of a molecule.

(.05)X(grams of total solution) = grams of acetic acid (grams of acetic acid)/ (mol. wt. of acetic acid(=60g/mol)) = mol. acetic acid (mol. acetic acid)/ (Liters of total solution) = molarity(M)
convert to mol, (divide by molar mass) then multiply by 22.4
Molarity = moles of solute/Liters of solution ( 450 ml = 0.450 liters) 5M C6H12O6 = moles C6H12O6/0.450 liters = 2.25 moles C6H12O6 (180.156 grams/1 mole C6H12O6) = 405.351 grams of glucose ( you do significant figures )
One mol is equal to molar mass in grams of a molecule.
Silver chloride - AgClAg (107.89 grams) + Cl (35.45 grams) = 143.34 grams
2.430g. That's one tenth the number of grams in one mole of Mg, which would be 24.30, which is also its atomic weight. No, that is not a coincidence. Atomic weight of an element is always equal to the number of grams of an element in a mole of the same element.
Molarity equals mole per liter M = mol/L So solve for moles by multiplying liters to the other side of the equation and you get: mol=ML Plug in your numbers mol=0.250M*2.00L mol=0.5 or 19,99855 grams = aprox. 20 grams
mol = mass/Mr rearrange mol x Mr = mass 2 x 126.9g = 253.8g
117(g K) * [1.008(g/mol H) / 39.098(g/mol K)] = 3.02 gram hydrogen
