What is the molarity of a NaOH solution if 32.47 mL is required to titrate 0.6013 g of potassium hydrogen phthalate (C8H5O4K)
Artist 52 [7]

Answer:

0.0907 M

Explanation:

Before you can calculate the molarity, you need to convert grams to moles (via molar mass) and convert mL to L.

(Step 1)

Molar Mass (C₈H₅O₄K):

8(12.011 g/mol) + 5(1.008 g/mol) + 4(15.998 g/mol) + 39.098 g/mol

Molar Mass (C₈H₅O₄K): 204.218 g/mol

0.6013 g C₈H₅O₄K             1 mole
------------------------------  x  ------------------  =  0.00294 moles C₈H₅O₄K
                                          204.218 g

(Step 2)

1,000 mL = 1 L

32.47 mL              1 L
---------------  x  -----------------  =  0.03247 L
                        1,000 mL

(Step 3)

Molarity (M) = moles / volume (L)

Molarity = 0.00294 moles / 0.03247 L

Molarity = 0.0907 M

Make a conclusion about the following question: What is the relationship between the volume of a gas and the pressure exerted on
Alinara [238K]

The relationship would be inversely proportional, meaning that as the volume increases, the pressure decreases, and the opposite is true as well, as the pressure increases, the volume decreases.
