What is the concentration of proteins in cells in M (mol/L)? Given information: The molar mass of the proteins is 50,000 g/mol. The dry weight \% of proteins in the cell is 15\%, the dry weight \% of water in the cell is 70\%, and con...
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. Calculate the amount of precipitate of BaSO4...
The molar mass of any solid, liquid, or gaseous substance is the number of grams of the substance in its molecular (molar) form that contains 6.0221367 X e^23 atoms of the substance (Avogadro's Number). This is because the mass of a substance is dependent on the molecular weight of the...
Calculate the mass of CO2 produced from the decomposition of 61.0 grams of NaHCO3. Decomposition Reactions: Decomposition reactions are those in which one single reactant gets decomposed and results in forming multiple products. Sometimes, to start this reaction, a cer...
Re: How do you calculate the molar mass? « Reply #1 on: February 18, 2008, 01:11:37 PM » Mikey, I will say that 8H2O is part of the composition and you should threat like that! the rest of the calculations is yours, I can write the whole process but the rules says that ...
