Determine the mass in grams of 0.750 mol of francium.

Mass = 167.25 g

Explanation:

Given dа ta:

Number of moles of francium = 0.750 mol

Mass of francium = ?

Solution:

Formula:

Number of moles = mass / molar mass

Mass = number of moles * molar mass

Molar mass of francium = 223 g/mol

Mass = 0.750 mol * 223 g/mol

Mass = 167.25 g
