Charles law states that volume of gas is directly proportional to temperature of gas at constant pressure and fixed amount of gas.
V / T = k
where V - volume , T - temperature in Kelvin and k - constant
where parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation
T1 = 25 °C + 273 = 298 K
T2 = 35 °C + 273 = 308 K
substituting values in the equation,
V = 5.17 L
new volume is 5.17 L
V / T = k
where V - volume , T - temperature in Kelvin and k - constant
where parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation
T1 = 25 °C + 273 = 298 K
T2 = 35 °C + 273 = 308 K
substituting values in the equation,
V = 5.17 L
new volume is 5.17 L
Answer:
0.020 moles of can be formed
Explanation:
1. First determine the number of moles of LiOH.
Molarity is given by the following expression:
Solving for moles of solute:
moles of solute = M * Liters of solution
Converting 175.0mL to L:
Replacing values:
moles of solute = 0.227M*0.175L
moles of solute = 0.040
Therefore there are 0.040 moles of LiOH
2. Then write the balanced chemical reaction and use the stoichiometry of the reaction to calculate the number of moles of produced:
As the problem says that there are excess of , the limiting reagent is the LiOH.
can be formed
