Aprecipitation reaction is caused by mixing 100. ml of 0.25 m k2cr2o7 solution with 100. ml of 0.25 m pb(no3)2 solution. when the precipitate forms, it is filtered from the mixture. how many moles of solid product are formed? 0.25 mol0.010 mol0.025 mol0.050 mol

0.025 mol

Explanation:

To calculate the number of moles for given molarity, we use the equation:

    .....(1)

Molarity of solution = 0.25 M

Volume of solution = 100.0 mL = 0.1 L

Putting values in equation 1, we get:

Molarity of solution = 0.25 M

Volume of solution = 100.0 mL = 0.1 L

Putting values in equation 1, we get:

The solid precipitate formed here is lead dichromate.

According to stoichiometry :

1 mole of lead nitrate produce= 1 mole of lead dichromate

So, 0.025 moles of lead nitrate will produce = of lead dichromate

Hence, the amount of solid product (lead dichromate) formed is 0.025 moles.
