You mix baking soda and vinegar together in a sealed container and watch as bubbles form. You find the mass of the products of the reaction to be 50 g. What was the total mass of the initial baking soda and vinegar that you started with? Explain.

DICH IT GO TO A DIFERENT CLASS AND WORK ON THAT ALL DAY THATS ALL U GOT TO DO BYE

Explanation:

1. for the first question, we must find the mass of the anhydrous salt, mgso₄. the molar mass for mgso₄·7h₂o is 246.47 g/mol, while that of mgso₄ is 120.37 g/mol.7.834 g mgso₄·7h₂o * 1 mol mgso₄·7h₂o/246.47 g * 1 mol mgso₄/1 mol mgso₄·7h₂o * 20.37 g mgso₄/mol = 0.647 g mgso₄

2. mass of water = mass of sample - mass of anhydrous salemass of water = 7.834 - 0.647 = 7.19 gpercent water in hydrate = 7.19/7.834 * 100 = 91.74%

thats how its supposed to be
