Answer 1

\(m_{Ca}=0,16605\times10^{-23}\times40=6,642\times10^{-23}\left(g\right)\)

\(m_{Mg}=0,16605\times10^{-23}\times24=3,9852\times10^{-23}\left(g\right)\)

\(m_{Al}=0,16605\times10^{-23}\times27=4,48335\times10^{-23}\left(g\right)\)

\(m_{Fe}=0,16605\times10^{-23}\times56=9,2988\times10^{-23}\left(g\right)\)

\(m_{Na}=0,16605\times10^{-23}\times23=3,81915\times10^{-23}\left(g\right)\)

\(m_O=0,16605\times10^{-23}\times16=2,6568\times10^{-23}\left(g\right)\)

\(m_S=0,16605\times10^{-23}\times32=5,3136\times10^{-23}\left(g\right)\)

\(m_N=0,16605\times10^{-23}\times14=2,3247\times10^{-23}\left(g\right)\)

\(m_{Cl}=0,16605\times10^{-23}\times35,5=5,894775\times10^{-23}\left(g\right)\)
