Q. Calculate the molar mass of MnO2. Q. Calculate the molar mass of C2H6 Q. Calculate the amount of precipitate of BaSO4 formed when 30 mL of 0.1 M BaCl2 is mixed with 40 mL of 0.2 M Al2(SO4)3. (Molar mass of barium = 137 g/mol, Molar mass of Al = 27 g/mol). Q. Calc...
Calculate the molar mass of the ionic compound chromium(II) bromide. For the substance barium nitride: i). Identify as molecular, ionic, or acid; ii). Write the formula of the compound; and iii). Show your setup and calculate the molar mass of the compound. ...
Now that you know what a mole is and what molar mass refers to, where do you find this number? You can find it for each element on the periodic table. If you look underneath the symbol for each element, you will find a number. The molar mass of elements is given by that number, ...
Re: How do you calculate the molar mass? « Reply #8 on: February 18, 2008, 09:49:07 PM » Just for the record, when you have H20 trapped like that, it's called a hydrate. Just a little snippet of info that might be useful to you sometime Logged Print...

As such, the molar mass of NaOH is 30.997 g/mol. What if you have a compound that has an element with a subscript? For example, MgCl2? In this case you would need to add the molar mass of magnesium and two times the molar mass of chlorine: ...
What mass of (NH4)2SO4 is required to prepare 750.0 mL of this solution? A solution is created by dissolving 14.0 grams of ammonium chloride in enough water to make 355 mL of solution. What is the molarity of this solution? Suppose you have a bot...
Molar mass = (" Weight of the substance x Molar volume")/("Volume of the substance at STP") Molar volume at STP = 2.24 xx 10^(2)m^(3) = 22.4 L (or) 22400 cc. Molar mass of the gas at STP = (23.2xx22.4)/20 = 25.984 g .
