Inefficiency of the material or engine causes the output work of a machine to be less
than the input work. It is governed by the second law of thermodynamics wherein
no product of work can produce 100 percent efficiency. Only the Carnot engine
can produce a 100 percent effieciency.

Explanation:</h3>
<u>Step 1: Define</u>
3.45 g Ba(ClO₃)₂
<u>Step 2: Identify Conversions</u>
Molar Mass of Ba - 137.33 g/mol
Molar Mass of Cl - 35.45 g/mol
Molar Mass of O - 16.00 g/mol
Molar Mass of Ba(ClO₃)₂ - 137.33 + 2(35.45) + 6(16.00) = 304.33 g/mol
<u>Step 3: Convert</u>
- Set up:
