What is the molarity of HCl if 34.81 mL of a solution of HCl contain 0.3297 g of HCl?
Temka [501]

Answer:

0.2598 M

Explanation:

Molarity is mol/L, so we have to convert the grams to moles and the mL to L. To convert between grams and moles you need the molar mass of the compound, which is 36.46g/mol.

0.3297gHCl*\frac{1molHCl}{36.46gHCL} = 0.00904279 mol HCl

34.81 mLHCl * \frac{1L}{1000L} = 0.03481 L HCl

\frac{0.00904279molHCl}{0.03481 L HCl} = 0.25977554 mol/L

Round to the lowest number of significant figures = 0.2598 M
