For 250 cm 3 of 0.1 M sodium carbonate solution, the mass required is: 106 x 0.1 x 250 / 1000 = 2.65 g Procedure Using a balance, measure accurately 2.65 g of pure anhydrous sodium carbonate on a clock glass. Multiply molarity by the solution volume (in liters) and the number 106—the molar mass of sodium carbonate—to calculate the mass of sodium carbonate needed. When calculating molecular weight of a chemical compound, it tells us how many grams are in one mole of that substance. Because the ashes of these sodium-rich plants were noticeably different from ashes of wood (once used to produce potash), sodium carbonate became known as "soda ash." assuming all solid dissolves, calculate the pH of the solution. I said that $$\frac{x}{\pu{105.99 g/mol}} + \frac{(0.107 - x)}{\pu{84.01 g/mol}} = \pu{0.00166 mol}\ \text{of carbonate}$$ In its anhydrous form, the molar mass is 105.98 g/mol. 0.009435 mol (Lab 8) How many moles of carbon dioxide were released from the reaction in flask 1?
