Ta có
m\(_{HCl}=0,1.36,5=3,65\left(g\right)\)
mdd =100+ 3,65=103,65(g)
C%=\(\frac{3,65}{103,65}.100\%=3,52\%\)
C\(_M=\)\(\frac{0,1}{0,1}=1\left(M\right)\)
Chúc bạn học tốt
mHCl = 0,1.36,5 = 3,65 g
mdd HCl = mHCl + mH2O = 100 + 3,65 = 103,65 g
C%dd HCl = \(\frac{m_{CT}}{m_{dd}}.100\%\) = \(\frac{3,65}{103,65}.100\%\) = 3,52 %
CM (dd HCl) = \(\frac{n}{V}\) = 0,1/0,1 = 1 M
