1.Start with the number of grams of each element, given in the problem.
2.Convert the mass of each element to moles using the molar mass from the periodic table.
3.Divide each mole value by the smallest number of moles calculated.
4.Round to the nearest whole number. This is the mole ratio of the elements and is.
Anion is an atom with a negative charge
so in this case it woulld be O2-
Answer:
Mass = 684.2 g
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
