Answer:

Produced energy =  2.925 × 10¹³ J

Explanation:

Given:

Mass of aspirin = 325 mg = 0.000325 Kg

Efficiency = 100%

Find:

Produced energy = ?

Computation:

According to light energy formula:

⇒ E = MC² ........   C = Speed of light = (3 × 10⁸)

⇒ E =  0.000325 × (3 × 10⁸)²            

⇒ E =  0.000325 × 9 × 10¹⁶

⇒ E =  0.002925 × 10¹⁶

⇒ E =  2.925 × 10¹³ J
