What is the mass in grams of 1mole of oxygen?
The mass of 2.000 mol of oxygen atoms is 32.00 grams.
A mixture of gases contains 0.25 mol oxygen gas 0.75 mol nitrogen gas and 1.50 mol carbon dioxide gas at STP The mole fraction of oxygen gas in this mixture is?
At STP (Standard Temperature and Pressure), the volume occupied by 1 mol of any gas is 22.4 L. Thus, 0.25 mol of oxygen gas occupies (0.25 mol) * (22.4 L/mol) = 5.6 L in the mixture. The total volume of the gas mixture can be found as the sum of the individual volumes of oxygen, nitrogen, and carbon dioxide. Then, the mole fraction of oxygen gas is the moles of oxygen gas divided by the total moles of all gases in the mixture.
How many moles of oxygen atoms are present in 5.00mol of diphosphorus pentoxide P2O5?
In one molecule of diphosphorus pentoxide (P2O5), there are 5 oxygen atoms. So, in 5.00 mol of P2O5, there would be 5.00 mol * 5 = 25.00 moles of oxygen atoms.
How many oxygen atoms are present in 40.0 grams of oxygen gas?
There are approximately 0.625 moles of oxygen gas in 40.0 grams. Since the formula for oxygen gas is O2, there are 0.625 moles x 2 = 1.25 moles of oxygen atoms. Therefore, there are approximately 1.25 x 6.022 x 10^23 = 7.53 x 10^23 oxygen atoms in 40.0 grams of oxygen gas.
How many atoms are present in 16g of oxygen gas?
To determine the number of atoms in 16g of oxygen gas, you first need to calculate the number of moles of oxygen using the molar mass of oxygen. Oxygen has a molar mass of 16g/mol. So, 16g of oxygen gas is equal to 1 mole of oxygen gas. One mole of oxygen gas contains approximately 6.022 x 10^23 atoms (Avogadro's number). Therefore, 16g of oxygen gas contains approximately 6.022 x 10^23 oxygen atoms.
Calculate the number of atoms of O contained in 16.0 pounds of O?
To calculate the number of oxygen atoms in 16.0 pounds of oxygen, first convert 16.0 pounds to grams (1 pound ≈ 453.592 grams). Then, calculate the number of moles of oxygen using the molar mass of oxygen (16.00 g/mol). Finally, use Avogadro's number (6.022 x 10^23 atoms/mol) to find the number of oxygen atoms.
How many oxygen atoms are there in 0.5 mol of CO2?
There are 1 mol of oxygen atoms in 1 mol of CO2. Therefore, in 0.5 mol of CO2, there are 0.5 mol of oxygen atoms. Number of molecules = 0.5*6.022 *10^23 ≈ 3.011 *10^23 molecules
What is the mass in grams of 1mole of oxygen?
The mass of 2.000 mol of oxygen atoms is 32.00 grams.
Which is more heavier - hydrogen gas or oxygen gas?
Oxygen gas is heavier than hydrogen gas. The molecular weight of oxygen (O2) is 32 g/mol while the molecular weight of hydrogen (H2) is 2 g/mol. Therefore, oxygen gas is heavier than hydrogen gas.
How many atoms of oxygen are in 0.50 mol of CaNO32?
The answer is 18,061.1023 atoms.
A mixture of gases contains 0.25 mol oxygen gas and 1.50 mol carbon dioxide gas at STP the mole fraction of oxygen gas in its mixture is?
The total moles of gas in the mixture is 0.25 + 1.50 = 1.75 mol. The mole fraction of oxygen gas is the moles of oxygen gas divided by the total moles, so 0.25 mol / 1.75 mol = 0.143. Therefore, the mole fraction of oxygen gas in the mixture is 0.143.
How many oxygen atoms in 2.15 mol of N2O?
There are 9.72 mol of oxygen atoms in 2.15 mol of N2O. This is because each molecule of N2O contains 2 oxygen atoms. So, you can calculate the number of oxygen atoms by multiplying the number of moles of N2O by 2.
How many moles of oxygen atoms are in 4.25 moles of calcium carbonate the chief constituent of seashells?
In calcium carbonate (CaCO3), there are 3 oxygen atoms per molecule. Therefore, in 4.25 moles of calcium carbonate, there would be 4.25 * 3 = 12.75 moles of oxygen atoms.
How many Oxygen atoms in 4.42mol of H2O2?
In 4.42 mol of H2O2, there are 26.52 moles of oxygen atoms. This is because each molecule of H2O2 contains two oxygen atoms.
Suppose you react 6.33 mol calcium with 4.00 mol oxygen gas What the number of moles of oxygen left over after the reaction is complete?
After the reaction is complete, all of the calcium will react with 3.165 mol (since calcium and oxygen react in a 1:1 ratio) of the oxygen gas. This means that there will be 4.00 mol - 3.165 mol = 0.835 mol of oxygen gas left over.
How many atoms of oxygen are in 3.120 grams of oxygen gas?
To find the number of oxygen atoms in 3.120 grams, we need to first calculate the number of moles using the molar mass of oxygen gas. The molar mass of oxygen gas is 32 g/mol. So, 3.120 grams is equal to 0.0975 moles. Each mole of oxygen gas contains 2 oxygen atoms, so there are 0.195 moles of oxygen atoms in 3.120 grams. Finally, using Avogadro's number (6.022 x 10^23), we find that 1.17 x 10^23 oxygen atoms are present in 3.120 grams of oxygen gas.
How many O atoms in 1.25 mol of SO2?
There are 4 oxygen atoms in 1 molecule of SO2. Therefore, in 1.25 mol of SO2, there would be 5 moles of oxygen atoms (4 * 1.25 = 5). Using Avogadro's number, we can determine that there are 3.01 x 10^24 oxygen atoms in 1.25 mol of SO2.
