A syringe contains 56.05 mL of gas at 315.1 K. What volume will that gas occupy if the temperature is increased to 380.5 K?

Marianna [84]

This is one of the ideal gas laws. Presumably the pressure remains the same so it is not part of the givens.

Formula

V / T = V1 / T1

Givens

V = 56.05 mL
T = 315.1 degrees Kelvin
V1 = x
T1 = 380.5 degrees Kelvin

Solution

56.05/315.1 = x/380.5 Simplify the left.

0.1779 = x / 380.5 Multiply both sides by 380.5

0.1779 * 380.5 = 380.5x/380.5

67.68 mL = x This is your answer

Question:<br> What is the molar concentration of 1.29 mol of KCL dissolved in 350 mL of solution?

STatiana [176]

Answer:

M = 3.69 M.

Explanation:

Hello there!

In this case, according to the given information, it turns out possible for us to calculate the molar concentration of the 1.29 moles of KCl in 350 mL of solution by recalling the mathematical definition of molarity as the division of the moles by the volume in liters, in this case 0.350 L; thus, we proceed as follows:

$M=\frac{1.29mol}{0.350L}\\\\M=3.69M$
