12.47 g of ammonium nitrate are dissolved in water, then diluted to 250 ml. what is the molarity of the resulting solution?

= 0.6224 M

Molarity is given by the formula;

Molarity = Number of moles/Volume

But moles = mass/Molar mass

Thus;

Moles = 12.47 g/80.043 g/mol

          = 0.1556 Moles

Therefore;

Molarity = 0.1556 moles/0.25

explanation:

i think option no d is the correct answer

let that person have a turn to speak : )
