the chemical formula for zinc nitrate is: zn(no3)2. calculate the molar mass of zinc nitrate. round your answer to 1 decimal place. g·mol^(-1)

Answer

Explanation:

Step1: Identify atomic masses

The atomic mass of Zn is approximately 65.38 g/mol, N is approximately 14.01 g/mol, and O is approximately 16.00 g/mol.

Step2: Calculate molar - mass contributions

For Zn in (Zn(NO_3)_2), there is 1 Zn atom, so the contribution is 65.38 g/mol. For N, there are 2 N atoms ((2\times14.01) g/mol = 28.02 g/mol). For O, there are 6 O atoms ((6\times16.00) g/mol = 96.00 g/mol).

Step3: Calculate total molar mass

Add the contributions together: (65.38 + 28.02+96.00=189.4) g/mol.

Answer:

189.4 g/mol
