Let's start by figuring out the amount in miles. From there, we can easily find the equivalent mass. Which equation do we need to find out how many moles of NH4Cl would there be in 500 mL of a 0.300 M solution of it?

A. n=C x V
B. C=V x n
C. C=n x V
D. n=C / V

Answer:

A. n= C x V

Explanation:

Molarity of a solution is the molar concentration of that solution. It can be calculated using the formula:

M = n/V

Where;

M = molarity (M)

n = number of moles (n)

V = volume (mL)

To calculate the number of moles from a given molarity value and volume, we say:

n = M × V

For this case of NH4Cl;

V = 500mL = 500/1000 = 0.5L

M = 0.300 M

n = 0.300 × 0.5

n = 0.15moles

Answer: n=CxV
