Answer:
660kcal
Explanation:
The question is missing the concentration of the glucose solution. Standard glucose concentration for IV solution is 5% or 5g of glucose every 100mL of solution.
We need to determine how many grams of glucose are there inside the solution. The number of glucose in 3.3L solution will be:
3.3L * (1000mL / L) * (5g/100mL)= 165 g.
If glucose will give 4kcal/ g, then the total calories 165g glucose give will be: 165g * 4kcal/ g= 660kcal.
To calculate the new pressure, we can use Boyle’s law to relate these two scenarios (Boyle’s law is used because the temperature is assumed to remain constant). Boyle’s law is:
P1V1 = P2V2,
Where “P” is pressure and “V” is volume. The pressure and volume of the first scenario is 215 torr and 51 mL, respectively, and the second scenario has a volume of 18.5 L (18,500 mL) and the unknown pressure - let’s call that “x”. Plugging these into the equation:
(215 torr)(51 mL) =(“x” torr)(18,500 mL)
x = 0.593 torr
The final pressure exerted by the gas would be 0.593 torr.
Hope this helps!
Reactants would be the missing word in the sentence because they make up the products in a chemical reaction

Answer:
The average pressure in the container due to these 75 gas molecules is
Explanation:
Here Pressure in a container is given as
Here
- P is the pressure which is to be calculated
- ρ is the density of the gas which is to be calculated as below
Here
mass is to be calculated for 75 gas phase molecules as
Volume of container is 0.5 lts
So density is given as
- is the mean squared velocity which is given as
Here RMS is the Root Mean Square speed given as 605 m/s so
Substituting the values in the equation and solving
So the average pressure in the container due to these 75 gas molecules is
