A. 32.1 g (32.1 g + 16.0 g + 16.0
x 100%
B. (32.1 g)(6.02 x 1023) 100 g
C. (32.1 g + 16.0 g+ 16.0 g) х 100%
32.1 g
D. 32.1 g (16.0 g + 16.0 g)
x 100%

Ans. : frostbite is when exposure to cold temperatures causes freezing to the skin or other tissues. it most commonly affects the hands, feet, and face. the longer areas are exposed to cold, typically the worse the frostbite. the water temperature used for rewarming a frostbitten part should be : (102 -105) f degrees.

The answer is 4 i don't know if its right let me see.

There is no reason to think the results are biased or not conducted properly but you should not assume the results are correct just because they were done in a laboratory so the answer would be c. it is likely to be reliable because the results support the conclusion presented.
