A balloon contains 7.36 g of oxygen gas (O2). How many oxygen molecules are in the balloon?
To find the number of oxygen molecules in the balloon, you can first calculate the number of moles of O2 using its molar mass (32 g/mol). Then, use Avogadro's number (6.022 x 10^23 molecules/mol) to convert moles to molecules. In this case, the balloon contains approximately 1.15 x 10^23 oxygen molecules.
If a balloon contains 0.15 moles of CO2 gas. how many molecules of CO2 are in the balloon?
The number of molecules is 0,90332112855.10e23.
IF it takes three breaths to blow up a balloon to 1.2 and each breath supplies the balloon with 0.060 moles of exhaled air how many moles of air are in a 3.0 balloon?
To blow up a 1.2 balloon, it requires 0.18 moles of exhaled air (3 breaths x 0.060 moles/breath). For a 3.0 balloon, which is 2.5 times larger, it would require 0.45 moles of air (0.18 moles x 2.5).
How many moles of helium will a 75.0-L balloon hold if a 27.5-L balloon holds 1.76 moles at the same temperature and pressure?
Using the ideal gas law, we can calculate the number of moles in the 75.0-L balloon by setting up a proportion using the volume and moles relationship between the two balloons. By cross-multiplying, we find that the 75.0-L balloon will hold approximately 4.85 moles of helium.
How many moles of H2O are present in 75.0g H2O?
There are 4.17 moles of H2O present in 75.0g of H2O.

How many moles of N2O molecules are present in a sample that contains 5.23 moles of nitrogen atoms?
Since each N2O molecule contains 2 nitrogen atoms, the number of moles of N2O molecules would be half of the moles of nitrogen atoms. Therefore, in this case, there would be 2.615 moles of N2O molecules present in the sample.

If a large balloon contains 224 liters of gas at STP then there is 100 mole of gas in the balloon How many moles of gas are in a balloon that is 560 liters at STP?
Using the ideal gas law, at STP (standard temperature and pressure), 1 mole of gas occupies 22.4 liters. Therefore, a balloon with 560 liters at STP would contain 25 moles of gas (560 liters / 22.4 liters/mole).
How many moles of H2O are present in 75.0g H2O?
There are 4.17 moles of H2O present in 75.0g of H2O.
