\(n_{O_2}=\dfrac{32}{32}=1\left(mol\right)\)
a, \(m_{H_2O}=36.1=36g\)
O2 + 2H2 \(\rightarrow\) 2H2O
pt: 1 2 2 (mol)
de: 1 2 (mol)
b, \(m_{H_2}=2.2=4g\)
nO2= 32/32=1 mol
a) Ta có: mH2O = VH2O*DH2O = 36*1=36g
b) nH2O= 36/18=2 mol
PTHH: O2 + 2H2 --to--> 2H2O
2 2
Theo PTHH, nH2=nH2O =2 mol =>mH2=2*2=4g
