A brand of soda has one of the highest quantities of sugar among popular soda drink packing 52 grams into each 12 oz can how many molecules of sugar are in one can of this soda

9.0 × 10²² molecules of sugar (sucrose)

Explanation:

Step 1: Given and required data

Step 2: Calculate the moles of sugar (n) in each can

We will use the following expression.

n = m/M = 52 g / (342.3 g/mol) = 0.15 mol

Step 3: Calculate the molecules corresponding to 0.15 moles of sugar

We will use Avogadro's number: there are 6.02 × 10²³ molecules in 1 mole of molecules.

0.15 mol × 6.02 × 10²³ molecules/1 mol = 9.0 × 10²² molecules

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%
