Question

Answer 1

a) 

Số phân tử C₄H₁₀ = 0,2.6.10²³ = 1,2.10²³ (phân tử)

\(m_{C_4H_{10}}=0,2.58=11,6\left(g\right)\)

\(V_{C_4H_{10}}=0,2.22,4=4,48\left(l\right)\)

b) 

Số nguyên tử Cu = 0,3.6.10²³ = 1,8.10²³ (nguyên tử)

\(m_{Cu}=0,3.64=19,2\left(g\right)\)

\(V_{Cu}=\dfrac{19,2}{8,9}=\dfrac{192}{89}\left(cm^3\right)\)

Answer 2

\(a,spt=0,2.6.10^{23}=1,2.10^{23}pt\\ m_{C_4H_{10}}=0,2.58=11,6\left(g\right)\\ V=0,2.22,4=4,48\left(l\right)\\ b,spt=0,3.6.10^{23}=1,8.10^{23}pt\\ m_{Cu}=0,3.64=19,2\left(g\right)\\V_{Cu}=\dfrac{19,2}{8,9}=2,1573\left(cm^3\right)\\ 2,1573cm^3=0,0021573l\)
