mCl=n.M=1.35,5=35,5gam
\(m_{Cl_2}=n.M=1.35,5.2=71gam\)
b)
mCu=n.M=1.64=64gam
\(m_{CuO}=n.M=1.80=80gam\)
c)
mC=n.M=1.12=12gam
\(m_{CO}=n.M=1.28=28gam\)
\(m_{CO_2}=n.M=1.44=44gam\)
d)
\(m_{NaCl}=n.M=1.\left(23+35,5\right)=58,5gam\)
\(m_{C_{12}H_{22}O_{11}}=n.M=1.\left(12.12+22.1+11.16\right)=342gam\)
