To find the number of molecules in 48.0 grams of oxygen gas (O2), you first need to determine the number of moles of O2 using its molar mass (32 g/mol). Then, you can use Avogadro's number (6.022 x 10^23 molecules/mol) to convert moles to molecules. The calculation would be: 48.0 g / 32 g/mol = 1.5 moles of O2, and 1.5 moles x 6.022 x 10^23 molecules/mol = 9.033 x 10^23 molecules of O2.
To find the mass of molecules in grams, you first need to determine the molar mass of the molecule. The molar mass of O2 is approximately 32 g/mol. Next, calculate the number of moles in 5.46x10^24 molecules using Avogadro's number (6.022 x 10^23 molecules/mol). Finally, multiply the number of moles by the molar mass to find the mass in grams.
Two moles of O2 molecules would have a mass of 64 grams (2 moles x 32 grams/mole = 64 grams).
The number of oxygen atoms is 0,188.10e23.
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.
The molar mass of O2 is 32 g/mol. To find the number of molecules in 48.0 grams of O2, we first need to find the number of moles using the formula: number of moles = mass / molar mass. Then, we can use Avogadro's number (6.022 x 10^23 molecules/mol) to convert moles to molecules.
10 grams of N2 would have a greater number of molecules than 10 grams of O2 because nitrogen (N2) has a smaller molar mass compared to oxygen (O2), so there would be more nitrogen molecules in 10 grams.

First, calculate the molar mass of O2 (molecular weight = 32 g/mol). Then, convert the given number of molecules to moles using Avogadro's number (6.022 x 10^23 molecules/mol). The result would be approximately 0.067 moles of O2.
Given: 7.6 x 1024 O2 moleculesKnown: 1 mole O2 molecules = 6.022 x 1023 molecules O2 moleculesConvert molecules to moles.7.6 x 1024 molecules O2 x (1mol O2/6.022 x 1023 molecules O2) = 13 moles O2 (rounded to two significant figures)

A mole of oxygen atoms has a mass of approximately 16 grams. A mole of O2 has a mass of approximately 32 grams. A mole is 6.02 x 1023 particles and as such a mole of oxygen atoms has only half the mass of a mole of oxygen molecules.
To calculate the mass of 1.5 moles of oxygen molecules (O2), you multiply the number of moles (1.5) by the molar mass of oxygen (O2). The molar mass of O2 is approximately 32 g/mol. So, the mass of 1.5 moles of oxygen molecules would be 1.5 moles * 32 g/mol = 48 grams.
