Question

Determine the mass in grams of 0.750 mol of francium.

Answer 1

Mass = 167.25 g

Step-by-step explanation:

Given data:

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
