Airida [17]

Answer:

The correct answer is option B.

Explanation:

As given ,that 30.24 mL of base was neutralize by 86.14 mL of acid which means that moles of base present in 30.24 mL are neutralized by moles of acid present in 86.14 mL.

After dilution of base from 30.24 mL to 50.0 mL .Since, the moles of base are same in the solution as that of the moles in solution before dilution. Moles of acid require to neutralize the base after dilution will same as a that of present moles of acid present in 86.14 mL.

Determine the mass of each sample 1.55 kmol sulfur trioxide
xxMikexx [17]

Explanation:

Given parameters:

Number of moles of the sulfur trioxide = 1.55kmol = 1.55 x 10³mole

Unknown:

Mass of the sulfur trioxide = ?

Solution:

To solve for the mass of the sample of sulfur trioxide:

  •  Find the molar mass of the compound i.e SO₃

          atomic mass of S = 32g

                                    O = 16g

              molar mass = 32 + 3(16) = 80g/mol

  • Use the formula below:

           mass of SO₃ = number of moles x molar mass

           mass of SO₃ =  1.55 x 10³ x 80 = 124000g or 124kg
