Answer 1

Atomic mass of P = ?

Answer 2

31

Answer 3

Molar mass of P4 will be 31*4 = 124

Answer 4

In my textbook it is given 132

The actual question is

Find the number of mole of phosphorous in 93.0 g of phosphorous assuming the molecular formula of phosphorous is P4

Answer 5

is it 0.75 moles ?

Answer 6

yes

Answer 7

Then what's the problem ?
Everything seems to be fine !

Answer 8

mass/molar mass

93/124=:(

Answer 9

Atomic mass of P = 31, so molar mass of P4 will be 4*31=124

Answer 10

yes

Answer 11

Now moles in 1 gram will be 1/124. So moles in 93 grams will be 93/124 = 0.75
