21)

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?

Answer 1

Produced energy = 2.925 × 10¹³ J

Step-by-step 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
