Calculate the alkalinity of a sample of lake water with pH 4.88 , a carbonate concentration of 103mol/L and a hydrogen carbonate concentration of 9775mol/L. Report your answer in mmol/L to one decimal place (though this may be more significant figures than is valid). Do not include units in your answer.
