Câu 1:
$n_{C_6H_{12}O_6}=\dfrac{36}{180}=0,2(mol)$
$C_6H_{12}O_6\to 2Ag$
$\to n_{Ag}=2n_{C_6H_{12}O_6}=0,2.2=0,4(mol)$
$\to m_{Ag}=0,4.108=43,2g$
Bảo toàn $Ag$: $n_{AgNO_3}=n_{Ag}=0,4(mol)$
$\to m_{AgNO_3}=0,4.170=68g$
Câu 2:
Axit axetic: $CH_3COOH$
Axit fomic: $HCOOH$
Glucozơ: $HOCH_2[CHOH]_4-CHO$
Fomanđehit: $HCHO$
Chỉ axit axetic không có nhóm $CHO$ hoặc đầu $HCO-$
$\to A$
Câu 3:
$n_{C_6H_{12}O_6}=\dfrac{27}{180}=0,15(mol)$
$\to n_{Ag}=2n_{C_6H_{12}O_6}=0,15.2=0,3(mol)$
$\to m_{Ag}=0,3.108=32,4g$
$\to C$
