Problem- A backpacker collects snow at 0 C, and places it in a cooking pot on a camp stove. It takes 643 kj of heat energy to melt the snow and bring the water to boiling. Assuming no heat loss, and neglecting the specific heat capacity of the pot, calculate the mass of snow that the backpacker collected.

Data: specific heat capacity of liquid water, c = 4.18 J/ g. K; and: H20(s) -> H20(l), /\H= /\H fusion = 6.02 kJ/mol

A) 1.92 kg B) 1.90 kg C) 1.52 kg D) 855g E) <800g

Please show work!!! Thanks

Explain the each and every step in detail for help
