You use an analytical balance to measure the mass of a weigh boat and record a mass of 1.5624 g. you then add some nahco3 to the weigh boat and give the weigh boat to your lab partner to measure. your lab partner mistakenly neglects to record all the sig figs on the balance and records a mass of 1.92 g (corrected rounded). what is the minimum number of grams of acetic acid that you would need to fully react with your nahco3? report your answer with appropriate sig figs and be sure to include units.
