What is the mass in grams of 3.1 mol of mercury, Hg Show Your work

621.83grams

Explanation:

Using the formula;

Mole = mass ÷ molar mass

Where;

Mole = mol

Mass = grams

Molar mass = g/mol

According to the information given in this question, number of moles = 3.1mol, mass of Hg = ?, Molar mass (MM) of Hg = 200.59g/lol

Hence, using mole = mass/MM

3.1 = mass / 200.59

mass = 200.59 × 3.1

Mass = 621.829

Mass = 621.83grams
