Help plsss! Will give brainliest if right A molecule contains 52.20 g of
manganese (Mn) and 3.80 g of carbon
(C). What is its empirical formula?

Mn3C

mols Mn = grams/atomic mass

mols C = grams/atomic mass

Now find the ratio to each other with the smallest being 1.00. The easy way to do that is to divide the smaller number by itself (which makes it 1.00), the divide the other number by the same small number. Round to whole numbers.

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.
