The concentration of carbon monoxide in an urban apartment is 48 g/m". what mass of carbon monoxide in grams is present in a room measuring 12.0
x 12.5 x 18.5 ft?
express your answer using two significant figures.

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.

i think slash and
