The amount of white phosphorus is 0.0199 moles
Explanation:
To calculate the number of moles, we use the equation:
We are given:
Given mass of white phosphorus = 2.478 g
Molar mass of white phosphorus = 124 g/mol
Putting values in above equation, we get:
Hence, the amount of white phosphorus is 0.0199 moles
