Crudeoil is a mixture and it comprises of compounds mostly hydri carbons i think
The equation for molarity is molarity equals moles divided by liters of solution. Knowing this, it's just simple algebra of 2 moles divided by .5 liters, equaling 4M (M standing for molarity).
It allows scientists to visualize the molecule they are working with more vividly.
It also allows them to see the ratio of atoms It contains which further allows
scientist to find the proportions of chemicals to mix together to maximize the
efficiency of a chemical reaction.
It’s easy, if the PH of any acidic solution = -Log[H+], where [H+] is hydrogen ion concentration, multiply each term by (-1) then raise each term as a power to (10), so it will become like this:-
[H+] = 10^(-PH)
