the molar mass of magnesium, mg, is 24.31 g/mol. how many moles of magnesium are in 2.37 grams of magnesium? ? mol mg
Answer
Answer:
0.0975 mol
Explanation:
Step1: Recall mole - mass formula
$n=\frac{m}{M}$ where $n$ is the number of moles, $m$ is the mass in grams, and $M$ is the molar mass in g/mol.
Step2: Identify given values
$m = 2.37$ g, $M=24.31$ g/mol
Step3: Substitute values into formula
$n=\frac{2.37}{24.31}\approx0.0975$ mol
