Answer:

The molarity of the solution is 0.048 M (option B)

Explanation:

<u>Step 1: </u>Data given

Sucralfate has a molar mass of 2087 g/mole

mass = 1g

volume = 10 mL

<u>Step 2: </u> Calculate moles of sucralfate

Number of moles = mass of sucralfate / Molar mass of sucralfate

Number of moles = 1 g / 2087 g/mole = 4.79 * 10^-4 moles

<u>Step 3:</u> Calculate molarity

Molarity = Number of moles / volume

Molarity = (4.79 * 10^-4 moles) / (10 *10^-3 L)

Molarity = 0.0479 M  ≈ 0.048 M

The molarity of the solution is 0.048 M (option B)

A balloon is filled with 35.0 L of helium in the morning when the temperature is 303 degrees kelvin. By 3:00 p.m., the temperatu
Anna007 [38]

Answer:

The new volume of the balloon is 38.5 L

Explanation:

Step 1: Data given

Volume at the start = V1 = 35.0 L

Temperature at the start = T1 = 303 Kelvin

Volume by 3pm = TO BE DETERMINED

Temperature by 3pm = 333 Kelvin

<u>Step 2: </u>Calculate the new volume

Charles' gas law says

V1/T1  = V2/T2

V 1  is the initial volume and T1 is the initial temperature

V2 is the final volume and T2 is the final temperature

35 L / 303 Kelvin = V2 / 333 Kelvin

V2 = 35L * 333 Kelvin / 303 Kelvin

V2 = 38.47L ≈ 38.5 L

The new volume of the balloon is 38.5 L
