The molar mass of carbon dioxide (CO2) is 44.01 g/mol. The molar mass of water (H2O) is 18.01 g/mol. A reaction uses 528 g of CO
Nataly [62]
The reaction that results from this is:

H2O + CO2 --> H2CO3

Stoichiometric ratio between water and CO2 is 1:1. So we can say that for every Mole of CO2, we need 1 Mole of water to produce 1 Mole of H2CO3. Thus as n=m/M we can find n = 528/44.01 = 11.997 ~ 12Mol.

therefore, we need 12 moles of water.

Answer:

Option e and f are possible

Explanation:

Since we know that 0.264 gallon = 1L ⇒ we change this in all equations.

8.08 L * A  =

a) 8.08 L * 0.264 gal / 8.08 L   = 0.264 gal = 1L

b) 8.08 L * 8.08 gallon / 0.264L = (8,08/ 0.264) L/0.264 L = 30.61 / 0.264 = 115.93 L *8.08 L

c) 8.08 L * 8.08 gallon / 1L = (8,08/ 0.264) L/1 L = 30.61 L * 8.08 L

d) 8.08 L * 0.264 L / 1 gallon =8.08 L * 0.264 L / 1 gal

e) 8.08 L * 0.264 gallon / 1L = 8.08 L *1L / 1L = 8.08 L

f) 8.08 L * 1L / 0.264 gallon = 8.08L * 1L / 1L = 8.08 L

The last 2 options are possible ( e and f )
