Agas made up of atoms escapes through a pinhole 0.155 times as fast as h2 gas. write the chemical formula of the gas.

Asolution is made by dissolving 2.3 moles of sodium chloride (nacl) in 0.155 kilograms of water. if the molal boiling point constant for water (kb) is 0.51 °c/m, what would be the boiling point of this solution? show all the steps taken to solve this problem.
