It can be made true by changing "cannot" to "can".
Answer:
mass (m) of the snow that the backpacker collected= 0.855 kg
Explanation:
Given that:
Q = 643 kJ = 643000 J
ΔHfusion = 6.02 kJ/mol = 6020 J/mol
number of mole of water H2O = 
c = 4.18 J/g⋅K
ΔT = 100 K
Since there is a phase change from solid to liquid; then :

ΔH = 
However without the given mass; we substitute
for the number of moles; so:
Q =



m = 855 g
m = 0.855 kg
mass (m) of the snow that the backpacker collected= 0.855 kg
Answer: As the temperature of the thermometer has increased it shows that that the reaction that has taken place was exothermic. In exothermic reactions heat is given out and temperature of the surroundings increases which is indicated by the increase in temperature of the thermometer.
