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.

organisms are more likely to be more preserved in mud than sand because mud is moist and wet, while sand is very dry.

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
