Calculate the number of moles of sulfuric acid in the total volume you used in the lab (i. e., 8.00 mL). Hint: Use the methodology of Question (1) above for finding out the molarity of the concentrated sulfuric acid first from its density (1.84 g/mL) and concentration (98.0% w/w), then find the number of moles. Show full work.

0.147 mol

Explanation:

Step 1: Calculate the volumetric concentration (Cv)

We will use the following expression.

Cv = Cg × ρ

Cv = 98.0 g%g × 1.84 g/mL = 180 g%mL

Step 2: Calculate the molarity of sulfuric acid

We will use the following expression.

M = mass solute / molar mass solute × liters of solution

M = 180 g / 98.08 g/mol × 0.100 L = 18.4 M

Step 3: Calculate the moles of solute in 8.00 mL of solution

8.00 × 10⁻³ L × 18.4 mol/L = 0.147 mol
