How many oxygen are there in CaCO3?
Calcium carbonate is a molecule that contains one atom of calcium, one atom of carbon, and three atoms of oxygen.
How many atoms of oxygen are present in 50 grams of CaCO3?
50.0 grams of CaCO3=50.0100.0=0.5 gram mol. 0.5 gram mole of CaCO3 contain oxygen atoms =0.5×3×6.022×1023=9.03×1023 atoms.
How many grams of oxygen are in CaCO3?
Explanation: In one mole of calcium carbonate, there are 40.08⋅g calcium metal, 12.01⋅g of carbon, and 3×15.999⋅g=48⋅g of oxygen.
How many atoms of CA are in 3 moles of calcium?
1 mole of any material contains the Avogadro number of particles, that is, 6.023×1023 particles. Hence, by ratio and proportion, 3.2 moles of calcium will contain 3.2×6.023×1023 Ca particles or atoms, which is 1.927×1024 Ca atoms.
How many oxygen atoms are present in 300g of CaCO3?
So given 3 moles of calcium carbonate, there are 3 moles of calcium, 3 moles ofcarbon, and 9 moles of oxygen atoms.
How many atoms of CaCO3 are in 100g CaCO3?
Answer Expert Verified
100 g of Calcium Carbonate (100,000 mg of Calcium Carbonate) has 3 moles of Oxygen atoms = 3 x 6.022 x 10^23 Oxygen atoms.
Which has greater number of carbon atoms 50 g of CaCO3 or 50g of Na2CO3?
Therefore, 50 g CaCO3 and 53 g of Na2CO3 have the same number of calcium carbonate and sodium carbonate molecules, which is half of Avogadro constant, 3.011 * 10 to the power 23. … Thus, 50 g of CaCO3 has more carbon atoms than 50 g of Na2CO3.
How is 1amu calculated?
1 amu = Average of the proton rest mass and the neutron rest mass. 1amu = 1.662 x 10–24g 0r 1.662 x 10–27kg. 1amu = 1.662 x 10–24g 0r 1.662 x 10–27kg.
Which has more number of atoms 50 gram of sodium or 50 gram of calcium?
∴ 50g of Na has more atoms.
