Answer: m = 50 g ZnSO4
Explanation: First is convert the moles of Zn to the moles of ZnSO4 by having their mole ratio which is 2:2 based from the balanced equation. Next is convert the moles of ZnSO4 to mass using its molar mass.
0.311 mole Zn x 2 moles ZnSO4 / 2 moles Zn
= 0.311 moles ZnSO4
0.311 moles ZnSO4 x 161 g ZnSO4 / 1 mole ZnSO4
= 50 ZnSO4
Answer:
Explanation:
they both break down the earth
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
Answer:
One can conclude that the metal is an alloy.
Explanation:
An alloy is a combination of metal that has two or more elements. Different metals are usually combined to give it more strength or make it more resistant to corrosion.
