Calculate the approximate volume of a 0.6000mol sample of gas at 288.15K and a pressure of 1.10atm.
11111nata11111 [884]

Answer:

The volume of the sample of the gas is found to be 12.90 L.

Explanation:

Given pressure of the gas = P = 1.10 atm

Number of moles of gas = n = 0.6000 mole

Temperature = T = 288.15 K

Assuming the volume of the gas to be V liters

The ideal gas equation is shown below

\textrm{PV} =\textrm{nRT} \\1.10 \textrm{ atm}\times V \textrm{ L} = 0.6000 \textrm{ mole}\times 0.0821 \textrm{ L.atm.mol}^{-1}.K^{-1}\times 288.5\textrm{K} \\\textrm{V} = 12.90 \textrm{ L}

Volume occupied by gas = 12.90 L

A scuba tank has a pressure of 195 KPa at a temperature of 10 °C. The volume of the tank is 350 L. How many grams of air is in t
marissa [1.9K]

The mass of air in the scuba tank is 841.614 g.

Using the ideal gas equation;

PV=nRT

P = pressure of the gas = 195 kPa

V = volume of the gas =  350 L

n = Number of moles of the gas = ??

R = molar gas constant = R = 8.314 J K-1 mol-1

T = temperature of the gas =  10 °C or 283 K

n = PV/RT

n = 195 * 350/8.314 * 283

n = 68250/2352.862

n = 29.00 moles

Number of moles = mass/molar mass

mass of air = Number of moles * molar mass

mass of air = 29.00 moles * 29g/mol

Mass of air = 841.614 g
