Question

total number of molecules in 3.92 g of mohr salt ​

Answer 1

Ammonium iron(II) sulfate, or Mohr's Salt, is the inorganic compound with the formula "(NH₄)₂Fe(SO₄)₂·6H₂O".

Number of molecules

= weight/gram molecular weight

Gram molecular weight of mohr salt is 392

Weight=3.92(given)

So n= 3.92/392 (n=WGMW)

n=1/100

n= 10^-2 moles are present in 3.92g of mohr salt
