Question

If you had a mixture that contained, what is the mathematical expression that would show percent NaO in the mixture? In this lab you will determine the percent composition of a mixture, you will be isolating NaCI and SO_2 from a mixture. you begin the day with a sample that has a total mass of 3.24g and after a few separations you have isolated the NaO from that sample. with the NaCI in hand you determine that it has a mass of 1.29g. what is I he percent NaO in this sample? 3. from the 3.24g sample where you extracted 1.29g of NaCI, after doing a little more work you finished the SO_2 recovery - you determined that t here was a total of 2.15g of SiO_2. what is t he percent SO_2 in your sample? 4. After looking at your data you realize that the masses of your recovered samples don't make a lot of sense, what is the total mass recovered (mass of SiO_2, mass of NaCI)? With the total mass of the recovered sample as well as the mass of the original sample, what is the percent recovered?

Explanation / Answer

1- Percentage of NaCl = [Amount of NaCl (gm) x 100] / Amount of Mixture in gm

2- % of NaCl = [1.29 x 100]/3.24 = 39.81 %
