Exactly 0.2220 grams of pure of Na2CO3 was dissolved in 100.0 ml of 0.0731 M HCI What mass in grams of CO2 were evolved?
Added by Endelyn S.
Step 1
First, we need to find the number of moles of Na2CO3. The molar mass of Na2CO3 is approximately 105.99 g/mol. So, the number of moles of Na2CO3 is 0.2220 g / 105.99 g/mol = 0.00209 mol. Show more…
