May 20, 2015 · Divide the mass of CO2 gas in the ﬂask by the number of moles of gas in the ﬂask to calculate the experimental molar mass of CO2. Experimental molar mass of CO2 _____ Calculation:7. Calculate the theoretical molar mass of CO2 from the periodic table. We will consider this to be the true value of the molar mass of CO2, because it is based on ...
Use the mass = molecular weight * mole equation to determine the theoretical mass of the product. The molecular weight of acetone is 58 g / mol: mass = 58 * 0.075 = 4.35 g. So from this reaction, we should get, theoretically speaking, 4.35 g of acetone. Nice! Now go on and conquer the world of theoretical yield calculations, you can do it!
