Answer:
Because CLEARLY, each mole of glucose, C6H12O6 contains 6⋅mol oxygen atoms.
Adaptation actually and also following control measures on how to avoid it from happening
Answer:
a. 167 mL.
b. 39.3 %.
Explanation:
Hello!
In this case, for the undergoing chemical reaction, since 45.0 g of aluminum react, based on the 2:3 mole ratio with sulfuric acid, we can compute the required moles as shown below:

Next, since the molarity of a solution is computed based on the moles and volume (M=n/V), we can compute the required volume of sulfuric acid as shown below:

That in mL is 167 mL.
Moreover, for the percent yield, we compute the grams of aluminum sulfate that are produced based on the required 2.50 moles of sulfuric acid:

Therefore the percent yield is:

Best regards!
pH=-lg[H⁺]
[H⁺] is the molar concentration of hydrogen protons
both solutions have the same concentration of the monoprotic acid so they will both have the same pH
pH=-lg0.1=1 because 10 at the power of -1 is equal to 0.1 but the sign is changed
