what is the molar mass of magnesium hydroxide, mg(oh)2?\n82.64 g/mol\n58.32 g/mol\n41.32 g/mol

Answer

Explanation:

Step1: Identify atomic masses

The atomic mass of Mg is approximately 24.31 g/mol, O is approximately 16.00 g/mol, and H is approximately 1.01 g/mol.

Step2: Calculate molar - mass of Mg(OH)₂

There is 1 Mg atom, 2 O atoms, and 2 H atoms in Mg(OH)₂. The molar mass $M$ is calculated as $M = 24.31+2\times16.00 + 2\times1.01$. $M=24.31 + 32.00+2.02$. $M = 58.33\approx58.32$ g/mol (due to rounding differences in atomic - mass values used).

Answer:

58.32 g/mol
