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.

intermolecular forces are the forces between molecules or particles.

there are two kinds of van der waals forces: weak london dispersion forces and stronger dipole-dipole forces.

in molecule of water there are dipole-dipole forces between negatively charged oxygen from one molecule of water and positively charger hydrogen of another molecule of water.

hydrogen bond is an electrostatic attraction between two polar groups that occurs when a hydrogen atom (h), covalently bound to a highly electronegative atom such as flourine (f), oxygen (o) and nitrogen (n) atoms.
