\(n_{CO}=n_{CO_2}=\dfrac{13.2}{44}=0.3\left(mol\right)\)
\(\Rightarrow m_{CO}=0.3\cdot28=8.4\left(g\right)\)
BTKL :
\(m_X=40+13.2-8.4=44.8\left(g\right)\)
\(n_{CO_2}=\dfrac{13,2}{44}=0,3\left(mol\right)\)
=> nCO = 0,3 (mol)
Bảo toàn KL: mX + mCO = mY + mCO2
=> MX = 40 + 13,2 - 0,3.28 = 44,8(g)
\(nCO_2=\dfrac{13,2}{44}=0,3mol\)
Bảo toàn C
\(\Leftrightarrow nCO=nCO_2=0,3mol\)
\(mCO=0,3.28=8,4gam\)
BTKL: \(m_X+m_{CO}=m_Y+mCO_2\)
\(m_X=\left(m_Y+m_{CO_2}\right)-m_{CO}\)
\(m_X=\left(40+13,2\right)-8,4\)
\(m_X=44,8gam\)
