-To calculate the mass of 0.2 moles of oxygen atom we should know the mass of a single atom of oxygen that is 16. -Therefore, the mass of 0.2 moles of oxygen atom is 3.2 grams and the mass of 0.5 moles of a water molecule is 9.0 grams.
What is mass of 0.2 mole of oxygen?
(a) Mass of one mole of oxygen atoms = 16 g. Then, the mass of 0.2 mole of oxygen atoms = 0.2 x 16g = 3.2 g.
What is the mass of 0.2 mole of water molecules?
∴ 0.2 mole of oxygen atoms = 16 × 0.2 = 3.2 g (b) 1 mole of water molecules = 18 g ∴ 0.5 mole of water molecules = 18 × 0.5 = 9 g 10.
What is the mass of 0.2 mole of chlorine gas?
Chlorine gas Cl 2, has a relative molecular mass of 71 because it is made up of two Cl atoms, each of Mr 35.5. A mole of chlorine gas has a mass of 71g, and contains two moles of chlorine atoms, each of mass 35.5g.
What is the mass of 0.5 mole of oxygen atom?
(i)0.5 mole of oxygen gas. (ii) 3.011 x 1023 atoms of oxygen. (iii) 6.022 x 1024 molecules of oxygen. (Given atomic mass of 0 = 16u; No = 6.022 x 1023 per mole)
How many grams are in 1 mole of oxygen?
Moles of a Substance and the Molecular Weight
The mass of oxygen equal to one mole of oxygen is 15.998 grams and the mass of one mole of hydrogen is 1.008 g.
How many atoms are in a mole of oxygen?
One mole of oxygen atoms contains 6.02214179×1023 oxygen atoms.
How many moles are in 50 grams of water?
There are 3 moles of O in 50 g.
What is the mass of 0.3 mole of oxygen atom?
Answer. Answer: Hence, the number of gram atoms of oxygen present in 0.3 moles of oxalic acid dihydrate is 0. 3×6=1.
What mass is 0.5 mole water?
Mass of 0.5 mole of water is 9g.
What is the mass in grams of 2.5 moles of chlorine gas?
Cl2 contains two Cl atom so molar mass will be 35 . 5 x2 that is 71 GRAM means 0ne mole of Cl2 has 71 gram so 2.5 mol will be equal to 2.5×71. Gram.
What is the mole of 12 gram of oxygen gas?
Therefore, 12 g of oxygen gas has 0.375 moles.
What is the mass of 0.1 mole of water?
Gram mole is same as mole. Molecular formula of water is H2O. So, adding the two we get the weight of one mole of water, which is 18g.
How many atoms are in 2 moles of oxygen?
1 Answer. There are 6×6.022×1023 atoms in 2.00⋅mol NO2(g) .
How many oxygen atoms are in 2 moles of CO2?
1 mole of carbon atoms per mole of carbon dioxide = 6.02 x 1023 carbon atoms. 2 mole of oxygen atoms per mole of oxygen atoms = 2 x 6.02 x 1023 oxygen atoms.
Which has maximum number of oxygen atom?
Answer:- O has largest number of atoms. Was this answer helpful?
