When aqueous solutions of k₂so₄ and pb(no₃)₂ are combined, pbso₄ precipitates. calculate the mass, in grams, of the pbso₄ produced when 1.66 ml of 0.2 m pb(no₃)₂ and 3.88 ml of 0.61 m k₂so₄ are mixed. calculate the mass to 3 significant figures.

0.101g PbSO₄

Explanation:

To know an amount of a product we have to know first how many moles of reactants we have.

The reaction is: ⇒

We can observe that per one mole of K₂SO₄ we need one mole of Pb(NO₃)₂, so Pb(NO₃)₂ is the limitant reactant and reaction will stop when it´s over.

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.

answers: to make sure that all of the broken pieces of tablet were added to the water, to allow for fair comparison of all three trials, with different particle sizes to avoid experimental error
