What volume of 15.6M NH4OH is needed to make 500.0 mL of 3.00M solution? a) 0.962 L b) 0.00962 L c) 0.026 L d) 0.0962 L

d) 0.0962 L

Explanation:

The problem describes a dilution process, meaning that we can solve it by using the following equation:

Where subscript 1 stands for the volume and concentration of the concentrated solution, and 2 for those of the diluted solution. That means that in this case:

We input the data:

And solve for V₁:

Finally we convert 96.2 mL to L:

The answer is thus option d).

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation
