Molar Mass (g/mol) Mg (Magnesium) 24.305 Cl (Chlorine) 35.453 I (Iodine) 126.90447 3. Compute Mass of Each Element Multiply the number of atoms by the atomic weight of each element found in steps 1 and 2 to get the mass of each element in MgCl2(I): Molar Mass (g/mol) Mg (Magne...
For example, MgCl2? In this case you would need to add the molar mass of magnesium and two times the molar mass of chlorine: Mg(24.305)+Cl(35.45×2)=95.211g/mol So the molar mass of MgCl2 is 95.211 g/mol. Using Molar Mass Now, you can tackle the question at the beginning of the...

You add 4.7 g of MgCl2 (MW = 95.2) to water. The final volume is 300 mL. What is the concentration in % solution? What is the concentration in Molarity? What molarity (M) is 90 mg/mL of glucose (MW = 180) solution? Calculate the molality and molarity ...
The basis of this lab is the reaction in which a known mass of magnesium metal reacts completely with excess hydrochloric acid to produce aqueous magnesium chloride and hydrogen gas according to the following balanced equation: Mg(s) + 2 HCl(aq) → MgCl2(aq) + H2(g) Purpose:To determine...
The number of moles of solute is given by the ratio of the mass of the solute to the molar mass of the same solute. We can write it as : {eq}n=\dfrac{m}{M} {/eq} Where, n is the number of moles m is the mass of a gi...
the compound and using the formula whole part mass = % for each element in the compound. The part is the mass of each individual element while the whole is the molar mass. If you know the molar mass and mass percents you can determine the empirical and molecular formula of the compound...
