Answer:
m = 2 * 10⁻³ kg

Explanation:
To answer this question, we will need to use Einstein's formula:
E = mc²
where:
E is the energy converted = 1.8 * 10¹⁴ J
m is the mass that we want to get
c is the speed of light = 3 * 10⁸ m/sec

Substitute with the givens in the above formula to get the mass as follows:
1.8 * 10¹⁴ = m * (3 * 10⁸)²
m = 2 * 10⁻³ kg

Hope this helps :)
