Answer:
2.34 molality
Explanation:
Mole weight of KOH ( using periodic table ...rounded to 3 s.f.) =
56.1 gm/mole
Number of moles in 43.2 g
43.2 g / 56.1 gm / mole =.770 mole
molality = .770 mole / .329 kg = 2.34 m
I believe it is C “Human activities such as mining and deforestation can change the Earth’s surface”
