A certain mass of ice at 00C melts into water at 00C and there by gains 1 kg mass. If initial mass of ice is m0 then –

A

m0 = 2.69 × 1011 kg

B

m0 = 1 kg

C

m0 = 2.69 × 1010 kg

D

m0 = 9 × 1016 kg

Answer

m0 = 2.69 × 1011 kg

Explanation

Solution

mc2 = m0L

1 × (3 × 108 12 = m0x (80 × 4200)

m0 = 2.67 × 1011 kg
