A 1.0 liter flask contains 90.1 moles of water vapor at 27.0 oC. What is the pressure of the gas?
Answer:
The pressure of the gas is 224839.8 atm
Explanation:
As we know
PV = nRT
Substituting the given values, we get -
P * 1 L = 90.1 moles * 8.314 4621(75). J K−1 mol−1 * 300

Answer:
Graphene is made of pure carbon.
Explanation:
It is a material in which the carbon atoms are arranged in a single layer, creating a honeycomb pattern. It should be stressed that this layer of carbon is only one atom thick, although some authors consider up to ten layers of carbon to be graphene.

Heat and temperature are two different but closely related concepts. Note that they have different units: temperature typically has units of degrees Celsius ( ∘ C ^\circ\text C ∘Cdegrees, start text, C, end text) or Kelvin ( Kstart text, K, end text), and heat has units of energy, Joules ( Jstart text, J, end text).
A gas occupies 12.3 L at a temperature of 40.0 K. What is the volume when the temperature is increased to 60.0 K?
Answer:
the volume is 18.45 L
Explanation:
The computation of the volume when the temperature is increased to 60.0 K is shown below:
Since the gas occupied 12.3 L at a temperature of 40.0 k
And, the volume when the new temperature is 60.0 k
So, the volume is
= 60.0 k × 12.3 L ÷ 40.0 k
= 18.45 L
hence, the volume is 18.45 L

What is the purpose of a buffer?
Answer: A buffer solution is a solution made to prevent the pH level of something from changing when you add a base or an acid to it. For example, if you put a buffer solution in a pool, and then you put chlorine in it, the chlorine's effect on the PH level will be suppressed.

What is the molarity of a solution where one mole of NaOH is added to 2000mL of water
Answer:
Molarity of a solution where one mole of NaOH is added to 2000mL of water is 0.0005
Explanation:
Molarity is the equal to number of moles of solute divided by total volume of solvent
Given -
Number of moles of solute i.e NaOH = 1
Total volume of solvent i.e water = 2000 mL
Molarity [tex]\frac{1}{2000} = 0.0005[/tex]

9.49.8 grams of Kl is dissolved in 1.00 kg of solvent. What is the molality?
Answer:
Molality = 9.498 mol k g − 1
Explanation:
A final way to express the concentration of a solution is by its molality. The molality ( m ) of a solution is the moles of solute divided by the kilograms of solvent. A solution that contains 1.0 mol of NaCl dissolved into 1.0 kg of water is a “one-molal” solution of sodium chloride.
molality = number of moles of solute/ mass of solvent in kg
number of moles of KI = mass of KI / molar mass of KI
number of moles of KI = 9.49.8 g / 1.00 g m o l − 1
number of moles of KI = 9.498 moles
molality = 9.498 moles / 1kg
molality = 9.498 mol k g − 1

If a response is towards a stimulus it's described as _______; if a response is away from the stimulus it's described as _____.
Answer: Positive tropism, negative tropism
Explanation:
Stimulus can be define as external and internal agent which generate a response in an organism. If the growth and action is towards the stimulus it is called as positive tropism. If the growth and action is away from the stimulus it is called as negative tropism. Example, the growth of the stem towards the sunlight is called positive tropism whereas the growth of the root away from the sunlight is called negative tropism. Here, sunlight is the stimulus.

Does anyone have any idea what this means lol
Answer:
29.42 Litres
Explanation:
The general/ideal gas equation is used to solve this question as follows:
PV = nRT
Where;
P = pressure (atm)
V = volume (L)
n = number of moles (mol)
R = gas law constant (0.0821 Latm/molK)
T = temperature (K
According to the information provided in this question;
mass of nitrogen gas (N2) = 25g
Pressure = 0.785 atm
Temperature = 315K
Volume = ?
To calculate the number of moles (n) of N2, we use:
mole = mass/molar mass
Molar mass of N2 = 14(2) = 28g/mol
mole = 25/28
mole = 0.893mol
Using PV = nRT
V = nRT/P
V = (0.893 × 0.0821 × 315) ÷ 0.785
V = 23.09 ÷ 0.785
V = 29.42 Litres
