mNaOH=40u
HCl + NaOH ---> NaCl + H₂O
36,5g HCl ------- 40g NaOH (dane z reakcji)
xg HCl ------------ 10g NaOH (dane z treści zadania)
x = 9,125g HCl --- tyle potrzeba nam czystego HCl
My jednak mamy do dyspozycji roztwór 10%, więc:
ms=9,125g
Cp=10%
mr=ms*100%/Cp
mr=9,125*100/10
mr = 91,25g roztworu HCl
