Question

What is the concentration of HNO3 if 5.00×10−2 mol are present in 905 mL of the solution?

Answer 1

Answer:

0.05525 M or 55.25 mM

Explanation:

Concentration = moles/volume

*Note that volume is expressed in L so you will need to convert mL > L here

$C= \frac{n}{V}\\C= \frac{0.05}{0.905}\\C=0.05525$
