Answer:
Explanation:
Hello,
In this case, one must consider that the ethanol's concentration in beer is defined as:
In such a way, since molarity is defined as:
One is asked to compute the moles, considering a basis of 5 milliliters of ethanol and 100 milliliters of beer, thus:
Now, the volume in molarity is required in liters, therefore:
Therefore, the molarity turns out:

Answer:
Most likely a mixed acidosis
Explanation:
Mixed acidosis is when you have metabolic acidosis and respiratory acidosis, the concentration of bicarbonate, that must be between 19.1 and 24.7, is 15, so it is below the lesser value. The partial pressure of carbon dioxide should be between 28.3 and 38.7, and client's partial pressure of carbon dioxide is slightly above the upper limit. Finally, pH sould be between 7.39 and 7.47, and client's pH is below the lesser limit. This all means that the blood is too acid.
Answer:
2.0 × 10² g
Explanation:
Step 1: Write the balanced equation
2 NO₂ + 0.5 O₂ ⇒ N₂O₅
Step 2: Calculate the theoretical yield, in moles, of N₂O₅
The molar ratio of NO₂ to N₂O₅ is 2:1.
6.0 mol NO₂ × 1 mol N₂O₅/2 mol NO₂ = 3.0 mol N₂O₅
Step 3: Calculate the theoretical yield, in grams, of N₂O₅
The molar mass of N₂O₅ is 108.01 g/mol.
3.0 mol × 108.01 g/mol = 3.2 × 10² g
Step 4: Calculate the real yield, in grams, of N₂O₅
real yield = theoretical yield × percent yield
real yield = 3.2 × 10² g × 61.1% = 2.0 × 10² g
