The formula of magnesium carbonate is MgCO3. It therefore has one atom each of magnesium and carbon and 3 atoms of oxygen. The gram molecular weight is therefore
24.305 + 12.011 + 3(15.999) = 84.313. This answer to the problem is twice this value, 168.626 grams, if the number "two" is considered to be exact.

∙ 15y agoFor this you need the atomic (molecular) mass of MgCl2. Take the number of moles and multiply it by the Atomic Mass. Divide by one mole for units to cancel. MgCl2= 95.3 grams
2.00 moles MgCl2 × (95.3 grams) = 190.6 grams MgCl2

How many formula units are there in 2.5 grams of Magnesium Chloride?
The relative molecular mass of magnesium chloride is approximately 60. The molar mass is therefore 60g per mole. Therefore there is 0.42mol of formula units in 2.5 grams.The formula mass of MgCl2 is 24.3 + 2(35.5) = 95.3Amount of MgCl2 = 2.5/95.3 = 0.0262molThere are 0.0262 moles of formula unit in 2.5 grams of magnesium chloride.To get the number (not in moles), multiply the amount in moles by the Avogadro's constant.
Can you calculate the number of moles of magnesium used grams permol?
Yes
How many moles of ions are produced by the dissociation of 1 mole NH4Br?
I assume that is 28.0 grams.28.0 grams MgCl2 (1 mole MgCl2/95.21 grams)= 0.294 moles magnesium chloride==========================Now,One mole Mg 2+ = 0.294 moles Mg 2+ ions=============================2 moles Cl - = 0.588 moles Cl - ions=========================
What is the mass in grams for 5 moles of Mg with the correct number of significant digits?
24.305 grams/mole Magnesium X 5 moles = 121.525 grams. The correct number of significant digits depends on the values given in the question. Since there was only one value (5), and it refers to a perfect integer amount (5 moles). The question of the correct number of significant digits is undefined and depends entirely on the number of significant digits available for the Atomic Mass of Magnesium. Since there are 5 significant digits in the Atomic mass used, the answer would be correctly stated as 121.53 grams to 5 significant digits.

Can you calculate the number of moles of magnesium used grams permol?
Yes
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
