Ineed someone to see if my answers are correct! if any are wrong let me know what the correct answers would be and how to get that answer! 1. how many moles of sodium chloride are in 28 grams od nacl? a. 265 mole naclb. 856 mole naclc. 479 mole of nacld. 1.2 mole nacl < my choice2. 734 grams of lithium sulfate (li2so4) are dissolved to make 2500 ml of solution what is rhe molaratiy? a. 2.67 mb. 4.56 mc. 3.89 m < my choiced. 1.78 m3. how many grams of cacl2 would be dissolved in 3.0 l of a 0.50 m solution of cacl2? a. 250 g cacl2 b. 166.5 g cacl2c. 113.65 g cacl2d. 98 g cacl2 < my choice4. suppose you had 58.44 g of nacl and you dissolved it in exactly 2.00 liters. the molarity if the solution would be 0.5 mtrue < my choicefalse 5. i would need 22g of naoh to make a 3.0 m solution using 250 ml of solvent.true < my choicefalse6. identify the solute: you have a .0195 m solution made from using 6.5 g of solute and 3 l of solvent. identify the solute by solving for molar weight.a. the solute is nacl because the molar weight is 58.43 g/mol < my choiceb. the solute is h2so4 because the molar weight is 98.06 g/molc. the solute is cacl2 because the molar weight is 111.11 g/mol

1. choose two of the acids listed, one monoprotic, the other diprotic. write the reactions that occur when each of them react with a solution of naoh. 2. to standardize a solution of naoh, one uses a primary standard called potassium hydrogen phthalate (khp for short). it is a monoprotic acid that can be obtained extremely pure and dried to a constant weight. it has a molar mass of 204.33 g/mol. suppose you weigh out 0.556 g of khp and dissolve it in water. it requires 14.48 ml of naoh solution to reach the endpoint. what is the concentration of the naoh solution? 3. the naoh solution from #2 above is used to titrate a diprotic acid solution of unknown concentration. 25.00 ml of the acid solution requires 26.54 ml of naoh solution. what is the concentration of the acid solution?
