The amount of energy (E) released when matter is converted to energy is proportional to mass of that object (m).

When E = 9 × 10¹³ Joules, m = 1 × 10^–3 kg

Calculate the mass, in kg when E = 1.8 × 10¹⁵ Joules

Give your answer in standard form

Your answer in standard form can be represented as q × 10^-q kg.
