The molarity of a solution made by placing 98 grams of H2SO4 insufficient water to make 500. milliliters of the solution is?       a. 0.5   b. 1    c. 2   d. 3

How many milliliters of 0.150 M NaOH are required to neutralize 50.0 mL of0.200 M H2SO4? The balanced neutralization reaction is:

A solution is made by dissolving 17.8 g of magnesium sulfite, MGSO3, in enough water to make exactly 100 ml of solution. Calculate the concentration (molarity) of MgSO3 in mol/L (M). (A) 1.71 mole MgSO3/L B 3.17 mole MgsO/L 2.71 mole MgSO3/L D) 2.17 mole MgSO3/L

If 35.0 g of C₂H₅OH (MM = 46.07 g/mol) are added to a 500.0 mL volumetric flask, and water is added to fill the flask, what is the concentration of C₂H₅OH in the resulting solution?

What is the molarity of Ca2+? of Cl-? 71. One mole of Na,S is represented as H0 where repre- sents Na and O represents S. Complete the picture showing only the sodium and sulfide jons. The water molecules need not be shown. + 1.00 L НО
