b. Pressure

Explanation:

Pressure is a physical effect that can change the boiling point of a substance.

Pressure is the force per unit area on a body.

  • A substance will boil when the vapor pressure of its heated molecules is greater than the atmospheric pressure.
  • The higher the atmospheric pressure, the higher the temperature and energy required to boil  a substance.
  • At high altitude, the atmospheric pressure is low and the boiling point of substances is lower.

Answer:

2812.6 g of H₂SO₄

Explanation:

From the question given above, the following data were obtained:

Mole of H₂SO₄ = 28.7 moles

Mass of H₂SO₄ =?

Next, we shall determine the molar mass of H₂SO₄. This can be obtained as follow:

Molar mass of H₂SO₄ = (1×2) + 32 + (16×4)

= 2 + 32 + 64

= 98 g/mol

Finally, we shall determine the mass of H₂SO₄. This can be obtained as follow:

Mole of H₂SO₄ = 28.7 moles

Molar mass of H₂SO₄ =

Mass of H₂SO₄ =?

Mole = mass / Molar mass

28.7 = Mass of H₂SO₄ / 98

Cross multiply

Mass of H₂SO₄ = 28.7 × 98

Mass of H₂SO₄ = 2812.6 g

Thus, 28.7 mole of H₂SO₄ is equivalent to 2812.6 g of H₂SO₄
