## 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 ^{–}^{24}g 0r 1.662 x 10^{–}^{27}kg**. 1amu = 1.662 x 10

^{–}

^{24}g 0r 1.662 x 10

^{–}

^{27}kg.

## Which has more number of atoms 50 gram of sodium or 50 gram of calcium?

∴ **50g of Na** has more atoms.
