This circle is centered at the point (3,2), and the length of its radius is 5. What is the equation of the circle?

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.

12. calculate the hydroxide ion concentration of a solution with ph = 3.25. show all calculations leading to an answer

The number of neutrons is equal to the atomic number minus the atomic mass. a. true b. false
