Question

18.3 g of HNO3 are dissolved in 2395ml H2O, what is the concentration of the H ions?

Answer 1

turn the grams of HNO3 into moles, and the mL of H2O into L, divide mol/L to get concentration

Answer 2

\[C=\frac{ n }{ v }\]
C=concentration
n=no.of moles
v=volume

Answer 3

to find the number of moles,
\[n=\frac{ m }{ M }\]
n=no. of moles
m=mass
M=Molar mas (mass number)
