The chemical equation below shows the burning of magnesium (Mg) with oxygen (O2) to form magnesium oxide (Mgo).
2Mg + O2 → 2Mgo
Niven wants to calculate the mass of Mgo that is produced by the burning of 28.0 g of Mg. What is the first step in
Niven's calculation?
O Balance the chemical equation.
O Convert grams of Mg to moles.
O Determine whether heat is given off by this reaction.
O Find the number of Mg atoms in the sample.

solute : a solute is a substance that is dissolved in another substance is known as a solvent. it is mixed with a special mixture know as homogeneous mixture.

solvent: a solvent is a substance that dissolved a solute, which results in a solution is known as solvent.
