Answer: The updated lemonade concentration is 3.90 M
Explanation:
To determine the number of moles based on molarity, we implement the formula:
.....(1)
The original molarity of the lemonade solution is 2.66 M
The total volume of the solution is 473 mL
Substituting values in equation 1 yields:
Next, we determine the new concentration of lemonade by employing equation 1:
The moles of lemonade calculates to be 1.26 moles
Volume of the solution after evaporation = (473 - 150) mL = 323 mL
Inserting values into equation 1 gives us:
Thus, the concentration of lemonade is now 3.90 M
Response:
0.8853 mL
Clarification:
Initially, we convert 13 lb to kg, remembering that 1 lb = 0.454 kg:
Next, we determine the required mg of acetaminophen to administer, applying the recommended dosage and infant's weight:
Finally, we compute the necessary mL of suspension, utilizing its concentration:
Result: 1.68 L of liquid nitrogen is generated during the gas liquefaction process.
Clarification:
This process involves transforming gaseous nitrogen into its liquid form.
The two states possess distinct densities, thus occupying varying volumes; however, the mass remains constant.
Step 1: Calculate the mass of nitrogen gas
Let’s determine the mass of nitrogen gas associated with 297 L.
The density formula is:
With a density of nitrogen gas at 4.566 g/L and a volume of 297 L, we can compute the mass of nitrogen gas as follows:
Using these values yields:
The mass of nitrogen gas calculates to be 1356 g.
Step 2: Derive the volume of liquid nitrogen from the mass obtained
The mass for liquid nitrogen remains the same.
With the density of liquid nitrogen at 809 g/L, we can substitute this into our formula to find the volume of liquid.
Therefore, the volume of liquid nitrogen is 1.68 L.
