The molar mass of NH4NO3 is 80.043 g/mol

What volume in liters of 0023 M NH4NO3 solution can be made using 25 g NH4NO3 The molar mass of NH4NO3 is 80043 gmol class=

Respuesta :

Answer:

14 L

Explanation:

To find the volume, you need to (1) convert grams to moles (via molar mass) and then (2) calculate the volume (via molarity equation). The final answer should have 2 sig figs to match the sig figs of the given values.

(Step 1)

Molar Mass (NH₄NO₃): 80.043 g/mol

 25 grams NH₄NO₃                 1 mole
-------------------------------  x  -------------------------  =  0.312 moles NH₄NO₃
                                           80.043 grams

(Step 2)

Molarity = moles / volume

0.023 M = 0.312 moles / volume                <----- Insert values

(0.023 M) x volume = 0.312 moles             <----- Multiply both sides by volume

volume = 14 L                                               <----- Divide both sides by 0.023
