Question

Calculate the relative molecular mass of Zn (NO3)2

Answer 1

Answer:

Okyu

Explanation:

Mass of Zn = 65

(NO3)2 = 124

$65 + (14 + 16 \times 2) \times 2 \\ 65 + 124 \\ = 184g mol$

Answer 2

Explanation:

Mass of Zn = 65

(NO3)2 = 124

\begin{gathered}65 + (14 + 16 \times 2) \times 2 \\ 65 + 124 \\ = 184g mol\end{gathered}

65+(14+16×2)×2

65+124

=184gmol
