Question

48.5 moles of P4O10 contains how many moles of P

Answer 1

So moles P = 4 x moles P4O10
= 4 x 68.5 mol
= 274 mol

Answer 2

Answer : The number of moles of phosphorous are 194 moles.

Explanation : Given,

Moles of
`P_4O_(10)` = 48.5 moles

By the stoichiometry in
`P_4O_(10)`, there are 4 moles of phosphorus and 10 moles of oxygen.

As, 1 mole of
`P_4O_(10)` contains 4 moles of phosphorous

So, 48.5 moles of
`P_4O_(10)` contains
`48.5* 4=194` moles of phosphorous

Therefore, the number of moles of phosphorous are 194 moles.
