An aspirin has a mass of 325 mg. If the mass of the aspirin could be converted to energy with 100% efficiency, how many joules of

energy would be produced?

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
