What is the result in kilojoules of 5.0x10 atoms emitting energy for 2.00 minutes if plank's 1 x atom (hint: same hint as #13) ball part 3x10" 18 constant is 6.626 x 10-14

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.

Which liquid (h2o, h2o + soap, or h2o + salt) has the strongest cohesion and adhesion? (need now plz)
