How many liters of a 6.0 M solution of acetic acid contain 0.0030 moles​

What are the concentrations of hydroxide and hydronium ions in a solution with a ph of 10.2?

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.

Can someone me with 6 to 10 plz this is for masteries test.
