Question

Giúp mình với, từ câu 5 trở xuống nha

Answer 1

Bài 5: 

n_{\(Na_2ZnO_2\)} = \(\dfrac{8,58}{143}=0,06mol\)

n_{\(Mg_3\left(PO_4\right)_2\)} =\(\dfrac{7,86}{262}=0,03mol\)

\(n_{CuSO_4}=\dfrac{7,42}{160}=0,046375\approx0,046mol\)

\(n_{CO_2}=\dfrac{26,88}{22,4}=1,2mol\)

\(n_{NO}=\dfrac{20,16}{22,4}=0,9mol\)

\(n_{NO_2}=\dfrac{16,8}{22,4}=0,75mol\)

\(n_{CuSO_4}=\dfrac{1,2.10^{23}}{6.10^{23}}=0,2mol\)

\(n_{Fe}=\dfrac{4,8.10^{23}}{6.10^{23}}=0,8mol\)

n_{\(Na_3PO_4\)} = \(\dfrac{15,3.10^{23}}{6.10^{23}}=2,55mol\)
