Solution contains 174 grams of lithium bromide in 360 grams of water, what is the mole fraction of lithium bromide

Explanation:

The mole fraction of a component in a mixture is the number of moles of the component divided by the total number of moles of all the components, multiplied by 100.

The symbol X is used to represent the mole fraction.

1. Convert masses in grams to number of moles

Formula:

a) Lithium bromide

b) Water

c) Total number of moles = 2.00 mol + 20.0 mol = 22.0 mol

2. Mole fraction of lithium bromide

altitude, density, pressure

air gets less dense the higher the altitude and also the air pressure is less as altitude rises.

gravity causes stares to cluster i think so
