Câu 1:
a) \(m_{Fe_2\left(SO_4\right)_3}=0,15.400=60\left(g\right)\)
b) \(m_{MgCl_2}=0,05.95=4,75\left(g\right)\)
c) \(m_{H_2}=0,2.2=0,4\left(g\right)\)
d) \(n_{N_2}=\dfrac{4,48}{22,4}=0,2\left(mol\right)\Rightarrow m_{N_2}=0,2.28=5,6\left(g\right)\)
e) \(n_{O_2}=\dfrac{6,72}{22,4}=0,3\left(mol\right)\Rightarrow m_{O_2}=0,3.32=9,6\left(g\right)\)
Câu 2:
a) \(V_{NO_2}=0,25.22,4=5,6\left(mol\right)\)
b) \(V_{CO_2}=0,3.22,4=6,72\left(mol\right)\)
c) \(n_{Cl_2}=\dfrac{3,55}{35,5}=0,1\left(mol\right)\Rightarrow V_{Cl_2}=0,1.22,4=2,24\left(l\right)\)
d) \(n_{N_2O}=\dfrac{1,32}{44}=0,03\left(mol\right)\Rightarrow V_{N_2O}=0,03.22,4=0,672\left(l\right)\)
