How many molecules of calcium carbonate are present in its one mole?
If its at STP (standard temperature & pressure) then i think 6 x 10^23 molecules
How many atoms in 1 mole?
There are 6.02 x 10 ^ 23 atoms or molecules of a substance in one mole of that substance. This is Avogadro's number.
How many atoms are in 189 g of calcium?
First, you need to figure out how many moles of calcium you have. One mole of calcium is 40.078g. So, divide 189g by 40.078. (189/40.078 = 4.716) Now, you can find out how many particles there are. There are 6.02*10^23 atoms in one mole. So, your answer will be 6.02*10^23 x 4.716 = 28.39 * 10^23.
How many particles are there in a mole of O2?

How many atoms are in 169 g of calcium?
To calculate the number of atoms in a sample of calcium, you need to first determine the moles of calcium in 169 g. Then, you can use Avogadro's number (6.022 x 10^23 atoms per mole) to find the number of atoms. The atomic mass of calcium is 40.08 g/mol, so 169 g of calcium is approximately 4.22 moles. Multiplying this by Avogadro's number gives approximately 2.54 x 10^24 atoms in 169 g of calcium.
How many atoms are in 125 grams of Calcium?
Well, Ca has an atomic mass of 40, so one mole of Ca (6.022x1023 atoms) equals 40g.To get 5kg of Ca, you would times the 40g (one mole) by 125.5kg of Ca has 125x(6.022x1023), or602200000000000000000000 atoms.
How many carbon atoms are in a molecule of calcium carbonate CaCO3?
A mole of H2 molecules contains 6.023 x 10^(23) H2 molecules or 2 moles of H atoms (since each molecules has 2 atoms). A mole of CaCO3 (calcium carbonate) has one mole (Avogadro number) of Ca atoms, one mole of C atoms and 3 moles of O atoms.
How many atoms are in 6 moles of calcium?
A mole contains 6.022 x 10^23 atoms, which is also known as Avogadro's number, and this number is same for each element. So, there are 2 x (6.022 x 10^23) = 12.044 x 10^23 atoms in 2 moles of Calcium.
How does the number of atoms in one mole of beryllium compare with the number of atoms in one mole of magnesium?
One mole of any element contains Avogadro's number of atoms, which is approximately 6.022 x 10^23 atoms. Beryllium and magnesium are both in Group 2 of the periodic table, so they have the same number of atoms in one mole.
How many calcium atoms are in 35.6 g of calcium?
To find the number of calcium atoms in 35.6 grams of calcium, you first need to calculate the number of moles of calcium. The molar mass of calcium (Ca) is approximately 40.08 g/mol. Thus, the number of moles in 35.6 g is 35.6 g ÷ 40.08 g/mol ≈ 0.887 moles. Since one mole contains Avogadro's number of atoms (approximately (6.022 \times 10^{23}) atoms/mole), the total number of calcium atoms is about (0.887 \times 6.022 \times 10^{23} \approx 5.34 \times 10^{23}) atoms.
How many moles of oxygen are in one mole of calcium carbonate?
1 mole CaCO3 (3 mole O/1 mole CaCO3) = 3 moles oxygen
How many atoms are in 115 grams of Calcium?
Avogadro's Number, 6.022 x 1023 gives the number of atoms in one mole. Calcium has an average atomic weight of 40.08 gmol-1 So one mole weighs 40.08 grams. 115 grams of Calcium will have (6.022 x 1023 / 40.08)*115 = 1.73 x 1024 atoms.
How does the number of atoms in one mole of beryllium compare with the number of Atoms in one full of magnesium?
One mole of beryllium contains the same number of atoms as one mole of magnesium, which is Avogadro's number, approximately (6.022 \times 10^{23}) atoms. This is true regardless of the element, as one mole of any substance always contains this fixed number of entities. Therefore, if you have one mole of beryllium and one mole of magnesium, both will contain the same number of atoms.
What does the number of atoms in one mole of each element do?
The number of atoms in one mole is the number of Avogadro: 6,022 140 857.10e23.
How many atoms are in 195 grams of calcium?
To find the number of atoms in 195 grams of calcium, you first need to calculate the number of moles of calcium using its molar mass. Calcium's molar mass is 40.08 g/mol, so there are 195g / 40.08 g/mol = 4.86 moles of calcium. Finally, one mole of calcium contains 6.022 x 10^23 atoms, so 4.86 moles x 6.022 x 10^23 atoms/mole = 2.95 x 10^24 atoms of calcium in 195 grams.
How many molecules of calcium carbonate are present in its one mole?
If its at STP (standard temperature & pressure) then i think 6 x 10^23 molecules
How many atoms of calcium are present in 60.8 g of calcium?
First you need to find how many moles of calcium that is. Since 1 mole of calcium is 40.078g you need to divide 60.8g by how much is one mole (60.8 / 40.078 = 1.517 moles). Once you know how many moles you have (1.517) you can find how many particles there are. There are 6.02 *10^23 atoms in one mole (Avagadro's number), so your final answer will be, 6.02*10^23 x 1.517 = 9.132 * 10^23
