Chemical Equation Balancer
Some can be relatively small; however, some can be thousands of square miles.
A compressed spring would have mechanical energy cause it generates from the force being built up in the spring
The balanced equation for the above reaction is as follows
P4 + 10Cl2 —> 4PCl5
P4 is the limiting reactant. Stoichiometry of P4 to PCl5 is 1:4
The mass of P4 reacted = 23.0 g
Number of P4 moles = 23.0 g/ 124 g/mol = 0.185 mol
According to the stoichiometry the number of PCl5 moles produced are 4 times the amount of P4 moles reacted
Therefore PCl5 moles = 0.185 x 4 = 0.74 mol
The Formula to find the number of moles is:
Number of Moles = Mass/ Molar Mass
Which means that Mass = Number of Moles * Molar Mass
We know that Number of Moles of Sodium Na =

moles
If you check the Periodic Table, Molar Mass of Sodium Na = 23g/mol
So, Mass =

=
So, the mass in grams of

mol of Sodium is
