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

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.

they all get energy from eating other animals, dead animals to be more precise.

hienas tends to steal pray from other animals. crows and vultures tend to eat dead animals and leftovers.

hope it ,
