how many oxygen molecules are there in 64g of oxygen gas?
355757
64 gm of Oxygen comprises of 3.556 moles. One mole of any substance has 6.022140857×10^23 molecules. Thus, 3.556 moles of Oxygen has 21.412 * 10^23 number of molecules.

88 g co2 is 2 moles of co2 ( 1 mole co2 = 44 gm) . Since 1 mole co2 has 2 moles of O atom 2 moles ie 88 gm will have 4 moles which is 4 times avogardos no of atom ie 4* 6.023 *10^23. What is the number of oxygen atoms in 0.2 mole of oxygen gas? How many atoms are present in 0.1 mole of oxygen?

1. There are 16 grams of oxygen in 18 grams of water. We can see from the formula for water, H2O, there are twice as many hydrogen atoms (each of atomic mass 1) as oxygen atoms (each of atomic mass 16).

64 gram of oxygen means two moles of oxygen so it has 2x 6.3 x10 raise to power 23 molecules.

Use the units to get answers like this: (6.02*10^23 molecules O2 / 1 mole O2) * (2 atoms O) / (1 molecule O2) * (1 mole O2 / 16 grams O2) → your answer in units of atoms O.

1 Answer. There are 1.8021⋅1024 molecules of CH4 in 48 grams of CH4 .
24788
Avogadro's number shows us that there are 6.022 x 10^23 molecules of CO2 in 1 mole of the gas. Therefore, there are 6.022 x 10^23 atoms of carbon and 12.044 x 10^23 atoms of oxygen in that 1 mole of CO2.
1062515
= N•/2 number of oxygen molecules. = 6.022 * 10^22. = 3.011 * 10^22 molecules.
1330280
Here, we are given with 16 g of oxygen. The number of molecules in 16 gm of oxygen are 0.5 (= 16/32 moles). Thus the number of molecules in 16 gm or 0.5 mole of oxygen gas are 0.5 x 6.023 x 10^(23) = 3.012 x 10^(23) molecules.

Oxygen has a molar mass of 16.0 g mol−1 , so 1 mole of oxygen atoms has a mass of 16.0 g . Therefore, carbon dioxide has a percent composition of 72.7% oxygen, i.e. for every 100 g of carbon dioxide you get 72.7 g of oxygen.

U mentioned element here so one gram atom of an element has 6.022×10^23 atoms :-) in oxygen(molar mass=16g/mol) 1g=1/16mol so it's 1/16 of the avogadro number.
