Answer:
0.15M
Explanation:
NaOH + HCl -->NaCl + H2O
moles of NaOH reacted with HCl
(0.5 × 30)/1000 = 1.5 × 10^ -3
so the moles of HCl reacted with NaOH
1.5 × 10^ -3
concentration of HCl = ( 1.5 × 10^ -3)/10 ×1000
Recall that a mole is defined as Avogadro's number of particles what the formula of caffeine basically tells us is that every molecule of caffeine you will have 8 atoms of carbon 10 atoms of hydrogen 4 atoms of nitrogen and 2 atoms of oxygen so if we have 0.3 moles of caffeine we will have 4*0.3 moles of nitrogen which is 0.12 and you got the idea
