Remember the moles eq'n
Moles = mass(g) / Ar (Realtive Atomic Mass.
Mass = 48.6 g
Ar = 24 ( From Periodic Table ).
Hence
Moles = 48.6/24
Moles = 2.025

What is the molarity of 80g magnesium chloride dissolved in 250ml of water?
MgCl2 Molarity = moles of solute/Liters of solution ( 250 ml = 0.250 L ) Get moles MgCl2 80 grams MgCl2 (1 mole MgCl2/95.21 grams) = 0.8402 moles MgCl2 Molarity = 0.8402 moles MgCl2/0.250 Liters = 3.4 M MgCl2 ----------------
How many grams of magnesium would be required to produce 4.00 grams of magnesium oxide?
4.00 grams of magnesium oxide is composed of 2.43 grams of magnesium (Mg) and 1.57 grams of oxygen (O). Therefore, to produce 4.00 grams of magnesium oxide, you would need 2.43 grams of magnesium.
How do I convert molar concentration to grams?
grams divided by the molecular weight to get to moles moles divided by volume to get molarity

The molarity of the solution is 0.5 M.
How many grams in magnesium?
The atomic mass of magnesium (Mg) is approximately 24.305 grams per mole.
What is the molarity of 31.1 grams of MgS in 853 mL of solution?

What is the molarity of a solution made with 128 grams of magnesium chloride dissolved in one liter of water?
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

What is the Molarity of a substance that contains 4.13 grams of magnesium bromide in 845 liters of a solution?
Molarity= mols/ L So, take 4.13g MgBr2 ( because Mg has a +2 charge and Bromide has a +1 charge) and divide it by 184.1 g MgBr2 which gives you .022 mols of MgBr2 then you divide .022 by 845 which gives you 2.65 M Molarity = 2.65M
How many grams of magnesium would be required to produce 4.00 grams of magnesium oxide?

What is the molarity of 48.6 g of magnesium (MG) IONS IN 2 l h 2o?
To calculate the molarity of magnesium ions (Mg²⁺) in a solution, first, determine the number of moles of magnesium. The molar mass of magnesium is approximately 24.31 g/mol. Therefore, 48.6 g of Mg corresponds to about 2.00 moles (48.6 g ÷ 24.31 g/mol). Molarity (M) is calculated as moles of solute divided by liters of solution. Thus, the molarity of magnesium ions in 2 liters of water is 2.00 moles ÷ 2 L = 1.00 M.
What is the molarity of a solution that contains 1.1 of lithium in 0.5 liters of solution?
If 1,1 is grams the molarity is 0,317.
