Để tác dụng vừa đủ với 3,83 gam hỗn hợp X cần 30 ml dung dịch HCl 1M.

Amino axit no

$\frac{m_{O}}{m_{N}}=\frac{80}{21}\, \, \, \, \, (1)$$\frac{m_{O}}{m_{N}}=\frac{80}{21}\, \, \, \, \, (1)$

$n_{H^{+}}=n_{N}\, (amino\, axit)$

$\Rightarrow n_{N}=0,03 (mol)$

$m_{N}=0,03.14=0,42(g)$

$(1)\Rightarrow m_{O}=\frac{0,42.80}{21}=1,6(g)$

$n_{O}=0,1(mol)$

$X+O_{2}\rightarrow CO_{2}+H_{2}O+N_{2}$

$\left\{\begin{matrix} C: x(mol)\\H:y(mol) \end{matrix}\right.\Rightarrow 12x+y=3,83-1,6-0,42$

$12x+y=1,81\, \, \, \, \, (2)$

$C\rightarrow CO_{2}$

x           x

$2H\rightarrow H_{2}O$

y              y/2

BT oxy:

$\Rightarrow 0,1+2.\frac{3,192}{22,4}=2x+\frac{y}{2}$

$(2),(3)\Rightarrow \left\{\begin{matrix} x=0,13\\y=0,25 \end{matrix}\right.$

$CO_{2}\rightarrow CaCO_{3}\downarrow$

0,13.100 = 13(g)
