Ta có: nmỗi khí = \(\frac{14}{22,4}=0,625\left(mol\right)\)
a) \(\Rightarrow m_{CH4}=n_{CH4}.M_{CH4}=0,625\times16=10\left(gam\right)\)
b) \(\Rightarrow m_{N2}=n_{N2}.M_{N2}=0,625\times28=17,5\left(gam\right)\)
c) \(\Rightarrow m_{C2H4}=n_{C2H4}.M_{C2H4}=0,625\times28=17,5\left(gam\right)\)
d) \(\Rightarrow m_{O2}=n_{O2}.M_{O2}=0,625\times32=20\left(gam\right)\)
