At SATP, a gas has a density of 1.78 g/L. What is the molar mass of the gas?

A balloon contains 0.158 mol of gas and has a volume of 2.46 L. If an additional 0.113 mol of gas is added to the balloon (at the same temperature and pressure), what is its final volume?

Determine the volume of O2 (at STP) formed when 50.0 g of KClO3 decomposes according to the following reaction. The molar mass for KClO3 is 122.55 g/mol.2 KClO3(s) → 2 KCl(s) + 3 O2(g)

at 25 degrees celcius and a pressure of 1.14 atm, a gas is found to have a density of 1.40 g/l. calculate the molar mass of the gas

1.12 mol sample of carbon dioxide gas at a temperature of 26.0 °C is found to occupy a volume of 20.8 liters. The pressure of this gas sample is _____mm Hg.

Consider this molecular-level representation of a mixture of gases. If the partial pressure of the diatomic gas is 0.450 atm, what is the total pressure? Ptotal = atm

The pressure of a gas results from which of the following? gas particles colliding with the container walls. the sum of the volumes of the particles being larger than the container volume. gas particles colliding with each other. The temperature of a gas is a measure of which of the following? the amount of space between gas particles. the kinetic energy of the gas particles. the number of gas particles. the volumes of the gas particles.

A 0.340 mol sample of an unknown gas contained in a 7.00 L flask is found to have a density of 1.74 g/L. The molecular weight of the unknown gas is

A balloon contains 0.158 mol of gas and has a volume of 2.46 L. If we add 0.113 mol of gas to the balloon (at the same temperature and pressure), what is its final volume?

Calculating partial pressure of a gas from a sketch Some N, gas is mixed with some O, gas, and the sketch below shows a representative sample of the mixture. The total pressure of the mixture is measured, and found to be 0.50 atm. key carbon hydrogen nitrogen sulfur oxygen chlorine Calculate the mole fraction and partial pressure of each gas in this mixture. Round your answers to 2 significant digits. You may assume each gas behaves as an ideal gas. gas mole fraction partial pressure atm N2 atm O2
