Hi how are you guys doing today???

What volume of a 2.00 m stock solution of naoh is needed to prepare 150. ml of 0.40 m solution?

What is the number of moles of chemical units represented by 9.03x10^24? and how do i show work? (dumb it down )

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.
