\(CT:C_{12}H_{22}O_{11}\)
\(M=12\cdot12+22+11\cdot16=342\left(đvc\right)\)
\(\%C=\dfrac{12\cdot12}{342}\cdot100\%=42.1\%\)
\(\%H=\dfrac{22}{342}\cdot100\%=6.43\%\)
\(\%O=51.47\%\)
a)
PTH = 12.12 + 22 + 16.11 = 342(đvC)
b)
$\%C = \dfrac{12.12}{342}.100\% =42,1\%$
$\%H = \dfrac{22}{342}.100\% = 6,43\%$
$\%O = 100\% -42,1\% -6,43\% = 51,47\%$
