Answer:
The volume of the container is 59.112 L
Explanation:
Given that,
Number of moles of Oxygen, n = 3
Temperature of the gas, T = 300 K
Pressure of the gas, P = 1.25 atm
We need to find the volume of the container. For a gas, we know that,
PV = nRT
V is volume
R is gas constant, R = 0.0821 atm-L/mol-K
So,

So, the volume of the container is 59.112 L
Answer:
The tools/instruments, the type of seed, the soil or planting products, the amount of germination time/days, and where the seedling is placed.
Explanation:
If anything but the temperature is changed, it can result in false results. For instance, if Tamera uses red corn for one but yellow corn for the other, it can change the germination rate. So can the type of soil, water or the amount of time each plant has to grow. If she changes thermometers or any other tool she uses, it may give her a different result than the ones she used before. And finally, if she moves the warm plant from the windowsill to her bedroom, it can mess with the results she gets from the heated sample.
Answer:


Explanation:
Hello,
In this case, we can compute the mole fraction of benzene by using the following formula:

Whereas n accounts for the moles of each substance, thus, we compute them by using molar mass of benzene and cyclohexane:

Thus, we compute the mole fraction:

Next, for the molality, we define it as:

Whereas we also use the moles of benzene but rather than the moles of cyclohexane, its mass in kilograms (0.08074 kg), thus, we obtain:

Or just 0.990 m in molal units (mol/kg).
Best regards.
