how does the total mass of each object increases the amount of force that is needed to get them moving at 5 m/s increase by about 200N demonstrate newtons 2nd law

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.

The element that has the greatest electronegativity is
