QUESTION 6 A student dissolves 10.0 grams of Ca(NO3)2, an ionic compound, into 500.0 mL of water. When it dissolves, one Ca(NO3)2 breaks into one equilavent of Cat2 cation in solution and two equivalents of the NO3-4 anion. The Molar Mass of Ca(NO3)2 is 164.09 g/mol. Therefore, what will be the Molarity of the Cat2 cation ? (report to three sig figs) 1 points Save Answer QUESTION 7 An non-ionic solute has a Molar Mass of 100 g/mol. If 10.0 grams is dissolved in 100 mL then it's Molarity will be__? Report to three sig figs.
QUESTION 4 How many milligrams of dextrose (Molar Mass 180.156 g/mol) are needed in order to make 375 ml of a 0.125 M dextrose solution? (1000 mL in 1 L. 1000 mg in 19. and answer to 3 sig figs) QUESTION 5 A student dissolves 100 grams of Ca(NO3)2, an ionic compound, into 5000 ml of water when it dissolves, one Ca(NO3)2 breaks into one equilevent of Ca 2 cation in solution and two equivalents of the NO3-1 anion The Molar Mass of Ca(NO3)2 is 164 09 g/mol Therefore, what will be the Molarity of the NO3 anion? (report to three sig figs)
