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.

Asubstance is a good conductor of electricity which of the following best explains a probable position of the substance in a periodic table

The number of moles of a given mass of a substance can be found without knowing its molecular formula or molar mass. true false
