Answer:
0.723 mol
Explanation:
Mole -
Moles is denoted by given mass divided by the molecular mass ,
Hence ,
n = w / m
n = moles ,
w = given mass ,
m = molar mass .
From the information of the question ,
w = 150.0 g
As we known the molar mass of lead is -
m = 207.2 g/mol
Hence , the value for the sample of mole can be calculated by using the above formula ,
n = w / m
putting the respective values ,
n = 150.0 g / 207.2 g/mol = 0.723 mol
