The mass of CO₂ present is 238.52g
<u>Explanation:</u>
Given:
Volume, V = 81.3 L
Pressure, P = 204 kPa = 204000 Pa
Temperature, T = 95°C
T = 95 + 273 K
T = 368 K
Mass of CO₂, x = ?
Molecular weight of CO₂ = 44 g/mol
According to gas law:
PV = nRT
where,
n = number of moles
n = given mass/ molecular mass
R = gas constant
R = 8.314 X 10³ L Pa K⁻¹ mol⁻¹
Substituting the value:
Therefore, the mass of CO₂ present is 238.52g
Answer:
In particular, organelles called chloroplasts allow plants to capture the energy of the Sun in energy-rich molecules; cell walls allow plants to have rigid structures as varied as wood trunks and supple leaves; and vacuoles allow plant cells to change size.
Explanation:
Answer : The molarity of a formic acid solution is, 0.0903 M
Explanation :
To calculate the molarity of formic acid, we use the equation given by neutralization reaction:
where,
are the n-factor, molarity and volume of formic acid which is
are the n-factor, molarity and volume of sodium hydroxide base which is NaOH.
As we are given:
Now put all the given values in above equation, we get:
Hence, the molarity of a formic acid solution is, 0.0903 M
<u>Answer:</u> The correct option is enough solvent to make 1.00 L of solution
<u>Explanation:</u>
A solution consists of solute and solvent. A solute is defined as the component present in a smaller proportion while the solvent is defined as the component that is present in a larger proportion.
Molarity is defined as the amount of solute expressed in the number of moles present per liter of solution. The units of molarity are mol/L. The formula used to calculate molarity:
.......(1)
We are given:
Molarity of solution = 0.500 M
Moles of solute = 0.500 moles
Putting values in equation 1, we get:
Hence, the correct option is enough solvent to make 1.00 L of solution
