What mass of barium chloride, BaCL2, is required to completely precipitate the barium sulfate from 35.0 ml of 0.200 m h2so4?
faltersainse [42]
The balanced equation would be (1)BaCl2 + (1)H2SO4 --> (1)BaSO4 + (2)HCl2
Then you should know that the coefficients stand for moles.
The thing is I'm not sure if H2SO4 is 35 ml or .200 m. 
Also, is this topic stoichiometry?

What volume of 7.25 mol/L stock solution in needed to make 3.84 L of 8.50 mol/L solution?
Serjik [45]

Answer:

4.50 L

Explanation:

First we <u>calculate how many moles are there in 3.84 L of a 8.50 mol/L solution</u>:

  • 3.84 L * 8.50 mol/L = 32.64 mol

Now, keeping in mind that

  • Concentration = Mol / Volume

we can calculate the volume of a 7.25 mol/L solution that would contain 32.64 moles:

  • Volume = Mol / Concentration
  • Volume = 32.64 mol ÷ 7.25 mol/L
  • Volume = 4.50 L

So we could take 4.50 L of the 7.25 mol/L solution and evaporate the solvent until only 3.84 L remain.
