2. Calculate the number of moles of sodium carbonate present in a mixture of sod

Question

2. Calculate the number of moles of sodium carbonate present in a mixture of sodium bicarbonate, sodium carbonate and a neutral component if 6.0 ml of 0.100 M HCl were used to titrate 0.200 g of this mixture with phenolphthalein as the indicator. 3. Calculate the mass of sodium carbonate present in the mixture in question 2. 4. Calculate the number of moles of sodium bicarbonate originally present in the unknown mixture in question 2, knowing that 15.0 ml of 0.100 M HCl were used in step 2 of the titration, using methyl orange as the indicator. I'm a little confused and could really use a step by step explanation. Thanks!!

Explanation / Answer

Use a periodic table, find out the molar masses and do this template (quantity given/ molar mass) x (mole ratio of balanced equation, which is given/ wanted) x ( molar mass of wanted substance/1 mol of such)
