Answer:
4 moles
Explanation:
The formula of finding moles is
moles = mass / molar mass, therefore
moles = 160 g / 40 g/mol = 4 moles
Water clarity is important in water habitats. The amount of sunlight that reaches underwater plants depends on water clarity. The plants will die if they cannot get enough sunlight, and we need the water to be clean and clear so the sunlight reaches the plants. Hope that helps :)
Fe2O3 + 3CO --------> 2Fe + CO2
1 : 3 : 2 : 3
13.3 <--- 40 ------> 26.6 ---> 40 ( mol)
n = m/M
m CO2 = n.M = 13.3 . 40 = 532 ( g)
p/s : i hope that this will help ( cause i'm not really good at english :}}} )
