Another student is attempting to make a saturated solution of KCl. The student added 30 g of KCl to 100 g of water at 60°C. What more does the student need to do to create a saturated KCl solution at 60°C?

Which statement describes both homogeneous mixtures and heterogeneous mixtures?

Compare and contrast the bohr model and the electron cloud models of the atom.

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.
