Answer:
0.142 moles.
You would have to convert the algorithm to a broken down version of the compound.
NH4NO3(aq] → NH+4(aq] + NO−3(aq]
The ammonium is removed for this case, concentration gets broken down to zero.
So here, if 1 liter is equal to 10 x 10 x 10 milliliters...
use the formula of n and c to help you figure out the moles.
C is equal to N divided by V, so in that case...
N equals C times V.
C times V is 0.425, or 17 over 40 in simplest form.
From there, multiply 17 over 40 by the current moles, cross out the liters, and multiply by 335, then, 10 to the power of -3. You have to flip it to negative, because it will cancel out either way. Change the equation by the liters, and you have 0.125
Hence, your correct answer is 0.125
