Answer:
144 g of phosphorus contain 4.65 moles.
Explanation:
Given data:
Mass of phosphorus (P) = 144 g
Number of moles = ?
Solution:
Formula:
Number of moles = mass/ molar mass
Molar mass of phosphorus is 31 g/mol
Now we will put the values in formula.
Number of moles = 144 g/ 31 g/mol
Number of moles = 4.65 mol
Thus, 144 g of phosphorus contain 4.65 moles.
