Answer: The molarity of solution is 1.39 M
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.
where,
n = moles of solute =
= volume of solution in L
Now put all the given values in the formula of molality, we get
Therefore, the molarity of solution is 1.39 M
Answer:
The pressure of the gas is 2.11 atm.
Explanation:
From the given,
Therefore, The pressure of the gas is 2.11 atm.
Boyle's law is used to find the new pressure after the gas is compressed from 1.00 L to 0.473 L. The original pressure is 1 atm at Standard Temperature and Pressure (STP). After the compression, the new pressure is approximately 2.12 atm.
The question relates to gas laws, specifically Boyle's law, which states that the pressure of a gas is inversely proportional to its volume when the temperature and amount of gas are held constant. At Standard Temperature and Pressure (STP; 273.15 K and 1 atm), one mole of an ideal gas occupancies a volume of about 22.4 L. In this case, the initial conditions are at STP, with a gas volume of 1.00 L, equating to a pressure of 1 atm. When this volume is compressed to 473 mL (or 0.473 L), the pressure can be determined using Boyle's law, i.e., P1V1 = P2V2. After substituting the values, we can solve for the new pressure (P2) which will be approximately 2.12 atm.
