Express the volume in milliliters to three significant digits.

Answer 1

page:01 Answers According to the given information, to find the how many milleliters are needed. Given, Ha Sou = 01129M Mass of Naoh a 0.250g. - Tie balanced equation is, Ha Sout a Naoh i Na, sou + algo. .. No. of moles of NaoH = mass of Naoh Molecular weight of Naot Here, Molecular weight of Naot : 89.994 glmol then, No.of moles of t1QOH - Orasoga 39.994 gimol :l. . of moles of NIQOH = 0.006a5 mol from the balanced equation, amole of Maot require i mole of Ha sou
