A combination reaction is given below: 3A 2B --5C If compound A has a molar mass of 159.7 g/mole and compound C has a molar mass of 57.6 g/mole, how many grams of compound C will be produced from 26.96 grams of compound A and excess compound B

16.2 g

Explanation:

Step 1: Write the balanced reaction

3 A + 2 B ⇒ 5 C

Step 2: Calculate the moles corresponding to 26.96 g of A

The molar mass of A is 159.7 g/mol.

Step 3: Calculate the moles of C produced from 0.1688 moles of A

The molar ratio of A to C is 3:5. The moles of C produced are 5/3 × 0.1688 mol = 0.2813 mol.

Step 4: Calculate the mass corresponding to 0.2813 moles of C

The molar mass of C is 57.6 g/mol.

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
