Question

Answer 1

Bài 1:

a, \(V_{N_2}=0,05.22,4=1,12l\\ b,V_{O_2}=1,5.22,4=33,6l\\ c,V_{CO_2}=0,06.22,4=1,344l\\ d,V_{H_2}=0,15.22,4=3,36l\)

Bài 2:

\(a,M_{Zn}=65\left(\dfrac{g}{mol}\right)\\ b,M_{Na}=23\left(\dfrac{g}{mol}\right)\)

\(c,M_{FeO}=56+16=72\left(\dfrac{g}{mol}\right)\\ d,M_{H_2SO_4}=1.2+32+16.4=98\left(\dfrac{g}{mol}\right)\)

\(e,M_{Al_2\left(SO_4\right)_3}=27.2+3.\left(32+16.4\right)=342\left(\dfrac{g}{mol}\right)\)

\(f,M_{Ca\left(OH\right)_2}=40+\left(16+1\right).2=74\left(\dfrac{g}{mol}\right)\)
