Complete the data table:

use these values:

the atomic mass of al is 27.0 g/mole.

the atomic mass of pb is 207.2 g/mole.

use two significant digits for your answers:

mass of al wire before reaction = 3.96 g

mass of al wire after reaction = 3.65 g

mass of al = g

moles of al lost = moles

mass of pb + filter paper = 4.26 g

mass of filter paper = 0.92 g

mass of pb = g

moles of pb formed = moles
