How many grams of pb are contained in a mixture of 0.135 kg each of pbcl(oh) and pb2cl2co3?

Mass of lead in is 107.74 g and mass of lead in is 103.6 g

Explanation:

To calculate the number of moles, we use the equation:

     .....(1)

Given mass of PbCl(OH) = 0.135 kg = 135 g   (Conversion factor:  1 kg = 1000 g)

Molar mass of PbCl(OH) = 259.66 g/mol

Putting values in equation 1, we get:

In 1 mole of PbCl(OH), 1 mole of lead, 1 mole of chlorine, 1 mole of hydrogen and 1 mole of oxygen atoms are present.

Moles of lead =

Calculating the mass of lead in PbCl(OH) by using equation 1, we get:

Molar mass of lead atom = 207.2 g/mol

Moles of lead atom = 0.52 moles

Putting values in equation 1, we get:

Mass of lead atom = 107.74 g

Given mass of = 0.135 kg = 135 g

Molar mass of = 545.3 g/mol

Putting values in equation 1, we get:

In 1 mole of , 2 moles of lead, 2 moles of chlorine, 1 mole of carbon and 3 moles of oxygen atoms are present.

Moles of lead =

Calculating the mass of lead in by using equation 1, we get:

Molar mass of lead atom = 207.2 g/mol

Moles of lead atom = 0.50 moles

Putting values in equation 1, we get:

Mass of lead atom = 103.6 g

Hence, mass of lead in is 107.74 g and mass of lead in is 103.6 g

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
