Calculate the number of moles in 128 g of sulphur dioxide.

Number of moles = 2 mol

Explanation:

Given data:

Mass of sulphur dioxide = 128 g

Number of moles = ?

Solution:

Formula:

Number of moles = mass/ molar mass

Molar mass of  sulphur dioxide:

Formula = SO₂

Atomic weight of sulfur = 32.065 amu

Atomic mass of oxygen = 16 amu

SO₂ = 32.065 + 16×2 = 64.065 g/mol

Number of moles = 128 g/ 64.065 g/mol

Number of moles = 2 mol

the correct answer would be d. hope this !

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
