Balance the equation with the correct coefficients.

Explanation:

In general, to balance an equation, here are the things we need to do:

Count the atoms of each element in the reactants and the products.

Use coefficients; place them in front of the compounds as needed.

87.62g = molar mass of strontium

1 moles of strontium
175.24g x

87.62 g of strontium

== 2 miles of strontium

I use the conversion 1 mol/87.62 g to convert the mass of an element to its molar form. I know that 87.62 grams equals one mol of strontium, but how about 175.24 grams of strontium? 2 mols of strontium equal 175.24 grams of strontium
