Question 14 An atom has 17 protons, 16 neutrons, and 17 electrons. What is its atomic mass?
17 amu
33 amu
34 amu​

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.
