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.

the answer would be c
