Agas has a pressure of 6.58 kPa at 540 K. What will the pressure be at 210 K if the volume
WARRIOR [948]

Answer:

P_2=2.6kPa

Explanation:

Hello there!

In this case, according to the Gay-Lussac's gas law, which illustrates the pressure-temperature behavior as a directly proportional relationship:

\frac{P_2}{T_2}=\frac{P_1}{T_1}

We can solve for the final pressure as shown below:

P_2=\frac{P_1T_2}{T_1}

Thus, we plug in the initial pressure and temperature and final temperature to obtain:

P_2=\frac{6.58kPa*210K}{540K}\\\\ P_2=2.6kPa

Which is not among the choices.

Regards!

An average human being has about 5.0 L of blood in his or her body. If an average person were to eat 37.7 g of sugar (sucrose, ,
Viktor [21]

Answer: 0.0220275 M

Explanation:

So, we are given the following data or parameters which are going to help in solving this particular Question/problem.

=> Averagely, we have the volume = 5.0 L of blood in human body .

=> Mass of sugar eaten = 37.7 g of sugar (sucrose, 342.30 g/mol).

Therefore, the molarity of the blood sugar change can be calculated as below:

The molarity of the blood sugar change = (1/ volume) × mass/molar mass.

Thus, the molarity of the blood sugar change = (1/5) × 37.7/342.30 = 0.0220275 M.
