Na2CrO4 + PbCL2<br> Formula in double replacement
Marta_Voda [28]

Na₂CrO₄ + PbCl₂ → PbCrO₄ + 2 NaCl

<u>Explanation:</u>

In a double displacement reaction, the reactants which are involved in the reaction exchanging their ions thereby produces 2 new compounds. Here sodium chromate and lead chloride are undergoing double displacement reaction, the ions exchanges their position there by forming sodium chloride and lead chromate. So the double displacement reaction is given as,

Na₂CrO₄ + PbCl₂ → PbCrO₄ + 2 NaCl

Calculate the molarity of a salt solution with a volume of 0.250L that contains 0.70 mol of NaCl. (SHOW WORK)
Kazeer [188]

Answer:

= 0.28M

Explanation:

data:

volume = 0.250 L

           = 0.250dm^3                       ( 1litre = 1dm^3)

moles = 0.70 moles

Solution:

      molarity = \frac{no. of moles}{volume in dm^3}

                 = 0.70 / 0.250

    molarity = 0.28 M
