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.
To convert grams to moles, divide the mass in grams by the molar mass of the substance. The molar mass of water is approximately 18 g/mol (1 g/mol for hydrogen and 16 g/mol for oxygen). So, 5.8 grams of water in 1 liter would be approximately 0.32 moles (5.8 g / 18 g/mol).
To determine the number of grams present in 0.20 mol of Na, you need to use the molar mass of sodium, which is approximately 23 grams/mol. Therefore, 0.20 mol of Na is equal to 0.20 mol x 23 g/mol = 4.6 grams of Na.
2.2 mol water = 2.2 (mol) * 18 (g/mol) water = 39.6 (mol*g/mol) = 40 g18 g/mol = mol mass of H2O = 2*H + 1*O = (2*1 + 16) g/mol

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 )
Silver chloride - AgClAg (107.89 grams) + Cl (35.45 grams) = 143.34 grams
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
To convert moles to grams, you need to use the molar mass of NaCl. The molar mass of NaCl is approximately 58.44 g/mol. Therefore, 1.6 mol of NaCl would be equal to 1.6 mol * 58.44 g/mol = 93.504 grams of NaCl.
One mol is equal to molar mass in grams of a molecule.
The volume of any gas at STP (standard temperature and pressure) is 22.4 L/mol. The molar mass of helium is 4.0026 g/mol. So, 84.6 grams of helium would be 84.6/4.0026 = 21.1 mol. Therefore, the volume of 84.6 grams of helium at STP would be 21.1 mol * 22.4 L/mol = 472.64 L.
At STP (standard temperature and pressure), 1 mol of any gas occupies 22.4 liters. The molar mass of carbon monoxides is 28.01 g/mol. So, the number of moles in 3.50 grams of carbon monoxide can be calculated. Then, using the ideal gas law, you can determine that 3.50 grams of carbon monoxide at STP would be approximately 0.125 moles and would occupy around 2.8 liters (0.125 moles * 22.4 liters/mol).
