Question

Answer the following stoichiometry question:

How grams in 25.36 moles of Aluminum, Al?
684.2 g
0.9400 g
1.064 g
1.527 x 10^25 g

Answer 1

Mass = 684.2 g

Step-by-step explanation:

Given data:

Moles of Aluminium = 25.36 mol

Mass of Al = ?

Solution:

Formula:

Number of moles = mass/ molar mass

Mass = number of moles × molar mass

Molar mass of Aluminium = 27 g/mol

Now we will put the values:

Mass = 25.36 mol × 26.98 g/mol

Mass = 684.2 g
