Four solutions are prepared and mixed in the following order: (1) Start with 100.0 mLmL of 0.100 MM BaCl2BaCl2 (2) Add 50.0 mLmL of 0.100 MM AgNO3AgNO3 (3) Add 50.0 mLmL of 0.100 MM H2SO4H2SO4 (4) Add 250.0 mLmL of 0.100 MM NH3   Write a net ionic equation for the reaction that occurs after the second step, third step, and fourth step.

An aqueous solution of a strong monoprotic acid (HA) contains 0.550 g of acid and is completely neutralized by 25.0 mL 0f 0.100 M Mg(OH)2 solution.  Calculate the molecular mass of acid.

If 40.7 g of CH₃OH (MM = 32.04 g/mol) are added to a 500.0 mL volumetric flask, and water is added to fill the flask, what is the concentration of CH₃OH in the resulting solution?

If 10. g of AgNO3 is available, what volume of 0.35 M AgNO3solution can be prepared?

A 25.0 mL solution of HBr is neutralized with 24.4 mL of 0.230 M Ba(OH)₂. What is the concentration of the original HBr solution?

15.67 mL of 0.5431 M H2SO4 is titrated with NaOH.  It takes 36.87 mL of NaOH to completely neutralize the acid.  What is the molarity of the base?

Suppose a group of volunteers is planning on building a park near a local lake.the lake is known to contain low levels of arsenic .Therefore prior to starting construction the group decides to measure the current level of arsenic in the lake.a) If a14.7cm3 Sample of lake water is found to have 168.3 gems mg Aersinic .What is concentration of arsenic in the sample in parts per billion ,assuming density of lake water is 1.00g/cm3

What volume (in mL) of a 2.60 M solution of CH₂OH must you add to a 1.00 L volumetric flask so that adding water to the mark will create a 0.150 M solution?
