Brooo we have the same name
We have atomic masses of: (omit units)
O=16
H=1
P=39
So:
O=58,5/16=3,65/1,21=3,01≈3
H=3,66/1=3,66/1.21=3,02≈3
P=37,8/31=1,21/1,21=1
So the empiric formula is:
H₃PO₃
3.5 M has 3.5 moles per litre
so we have one litre, so we need 3.5 moles
moles = mass/molarmass
3.5 * 23 = 80.5
The correct answer would be c
