Calculate the number of moles of solute in 95.71 mL of 0.1495 M K2Cr2O7(aq).

If 25.00 mL of 3.00 M HCl(aq) is diluted with water to a volume of 750.0 mL, what is the molarity of the diluted HCl(aq)? Don't write the units of measure (M=mol/L) in the box; only the numerical value of the answer, using the standard notation.

What volume of 0.200 M HNO3(aq) is required to react completely with 0.0150 moles of NaOH?

How many grams of oxalic acid, H2C2O4, are required to prepare 750. mL of a 0.250 M oxalic acid solution?   Report your result in decimal notation and to the proper number of significant figures.

A solution of NaCl(aq) is added slowly to a solution of lead nitrate, Pb(NO3)₂(aq), until no further precipitation occurs. The precipitate is collected by filtration, dried, and weighed. A total of 10.67 g PbCl₂ (s) is obtained from 200.0 mL of the original solution. Calculate the molarity of the Pb(NO3)₂(aq) solution. concentration: M

The amount of I, (aq) in a solution can be determined by titration with a solution containing a known concentration of S₂O3(aq) (thiosulfate ion). The determination is based on the net ionic equation 2 S₂O3(aq) + ₂ (aq) → S₂O²(aq) + 31 (aq) Given that it requires 35.5 mL of 0.440 M Na₂S₂O3(aq) to titrate a 30.0 mL sample of I3 (aq), calculate the molarity of I3 (aq) in the solution. [1] = M

Calculate and describe how to prepare 100.0 mL of 4.00 M NaCl(aq).

What mass (g) of NaOH is required to make 262 ml of 0.41 M NaOH(aq) solution?

570.0 mL of 0.4820 M CaCl2 is combined with 182.0 mL of aqueous 219.40 mM LICI. What is the chloride ion (CI) concentration in the resulting solution? Assume that the volumes of the two solutions are additive. Express your answer in units of millimolarity (mM) using at least three significant figures.

Hydrochloric acid solution is commonly found on laboratory shelves at a concentration of 6.00 M.  How many mL of this concentrated HCl would you dilute in order to prepare 500. mL of 1.24M HCl(aq)
