The answer is 0,615 moles.
8,23.1023 atoms Mg is equivalent to 1,366 moles.
There are 18.9 moles in 225.8 mg. This is a math problem.
1.346 grams Mg (1 mole Mg/24.31 grams) = 0.05537 moles magnesium
This is equivalent to 1,4 moles.
The molar mass of oxygen is 32 g.1,2 mg oxygen is equal to 0,0000375 moles.

There are 2.75 equivalents of Mg^2+ present in a solution that contains 2.75 mol of Mg^2+. This is because the number of equivalents is equal to the number of moles for ions with a +2 charge.
This is equivalent to 1,4 moles.
The molar mass of oxygen is 32 g.1,2 mg oxygen is equal to 0,0000375 moles.
To calculate the moles of gas produced, first find the moles of Mg reacting by dividing the mass by the molar mass of Mg. Next, determine the mole ratio of Mg to gas produced from the balanced chemical equation of the reaction. Finally, multiply the moles of Mg by the mole ratio to find the moles of gas produced.
14,84 g magnesium are equivalent to 0,61 moles.
