You are carrying out an experiment to determine the MW of a solid acid with the generic formula H3A. You weigh out 0.362 g of the solid acid in a weigh boat and transfer it to a 125 mL Erlenmeyer flask. After dissolving the acid in 25 mL of distilled water, you add 22.51 mL of 0.343 M Sr(OH)2 (aq) solution with a buret until your indicator changes color at the equivalence point. What is the molar mass of the solid acid in units of g/mole? Enter your answer with at least 4 significant digits (Canvas sometimes truncates zeros so assume that all numbers in this question have at least 4 sig figs (ie if Canvas tells you there are 12.3 mL assume 12.30 mL). This question will require precision so don't round any numbers until your final answer.
