Calculate the molarity of 0.300 mol of na2s in 1.75 l of solution.

calculate the molarity of 31.3 g of mgs in 955 ml of solution

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.

What is the lowest number energy level where a d sublevel is found

Areaction is first order with respect to reactant x and second order with respect to reactant y. which statement describes the rate law for this reaction?
