What is the mass of 2.30 ×1022 molecules of naoh (molar mass = 40.0 g/mol)?

1.52 g NaOH

Explanation:

The molar mass M is a physical property defined as the mass of a given substance (chemical element or chemical compound) divided by the amount of substance.

Molar mass of NaOH is 40.0 g/mol

40.0 g/mol contains 6.022 × 10²³ molecules

∴ 2.30 × 10²² molecules will contain (2.30 × 10²²) * (40.0)/6.022× 10²³

                                                             = 1.52 g NaOH

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?
