How many moles of Csl must be dissolved into 800 ml of a 0.40 M
solution?

0.32 moles  of Csl must be dissolved into 800 ml of a 0.40 M  solution.

Explanation:

Data given:

volume of the Csl solution = 800 ml or 0.8 litres

molarity of the solution = 0.40 M

number of moles of Csl = ?

molarity is calculated by using the formula:

molarity =

rearranging the equation to get the number of moles:

number of moles = molarity x volume in litres

putting the values in the equation:

number of moles = 0.4 x 0.8

number of moles of Csl in the solution is 0.32

therefore 0.32 moles of Csl should be dissolved in 800 ml of the solution to obtain molarity of 0.4 M.

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).
