Please help me! I'd really appreciate it thanks Show all work, include units, subscripts, and superscripts, correct particle name, etc. as demonstrated in class.

Calculate the Molar mass of magnesium thiotellurite (Mg3TeS5).

Determine the mass of 2.30 moles of KMnO4.

Find the mass of 5.0 x 1020 formula units Mg3TeS5.

the molecules move in straight line until they collide with each other or with the walls of the container. collisions are perfectly elastic; when two molecules collide, they change their directions and kinetic energies, but the total kinetic energy is conserved.

explanation:

the answer for sodium is 0.186

the answer for rubidium is 0.251

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.
