The more finely divided the solid is, the faster the reaction happens. A powdered solid increases the rate of the reaction than the same mass present as a single lump. The powdered solid has greater surface are than the single lump.
Given parameters:
Mass of H₃PO₄ = 49g
Unknown:
Number of moles = ?
Solution:
To find the number of moles of a given specie;
number of moles =
Molar mass = 3(1) + 31 + 4(16) = 98g/mol
Input the parameters and solve;
Number of moles = = 0.5mole
The number of moles is 0.5mole
