How many atoms are in 133g of calcium?
To find the number of atoms in 133 grams of calcium, first, calculate the number of moles using its molar mass, which is approximately 40.08 g/mol. Dividing 133 g by 40.08 g/mol gives about 3.31 moles of calcium. Then, multiply the number of moles by Avogadro's number (approximately (6.022 \times 10^{23}) atoms/mol) to find the total number of atoms, which is about (2.00 \times 10^{24}) atoms of calcium.
What is the total number of atoms in 12.7mol Ca?
12.7 moles calcium (6.022 X 10^23/1 mole Ca) 7.65 X 10^24 atoms of calcium in 12.7 moles.
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 calcium are in 15.5 g calcium chloride?
If grams/molar mass=moles, then first the molar mass of the compound must be found. CaCl2 has a molar mass of 110.984. Divide the number of grams, 15.5, by 110.984, and you get the number of moles. Now, seeing as calcium is not diatomic like oxygen or chlorine, there needs to be no conversion between the number of moles of calcium in the compound and the number of moles of calcium outside of the compound. atoms, the number of calcium atoms in the compound divided by one mole of the compound will give us the ratio. Conveniently enough, that ratio is one calcium atom per molecule of calcium chloride, meaning that for every one mole of calcium chloride, 1 mole of pure calcium can be extracted. So once you find the number of mole of CaCl2, that is the number of moles of calcium as well. This may be a little difficult to grasp, but I'm sure that your teacher, if you're a student, will be able to explain why rather well.
How many atoms does Calcium Nitrate have?
6,022 x 1023 atoms/mole. Calcium nitrate = Ca(NO3)2 .There are 1 mole of calcium making 6,022 x 1023 atoms of calcium.There are 2 moles of nitrate-ions and each nitrate-ion is made up of 1 mole nitrogen, and 3 moles of oxygen. Thath means that the nitrate ion in calcium nitrate has 6 moles oxygen and 2 moles of nitrate:Atoms of nitrogen: 6,022 x 1023 moles-1 x 2 moles = 1,2044 x 1024 atomsAtoms of oxygen: 6,022 x 1023 moles-1 x 6 moles = 3,6132 x 1024 atoms
How many atoms ar ein 133g of calcium?
To calculate the number of atoms in 133g of calcium, we first need to determine the number of moles of calcium present. The molar mass of calcium is 40.08 g/mol. By dividing 133g by the molar mass of calcium, we find the number of moles. Finally, we can use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles to atoms, giving us the total number of atoms in 133g of calcium.
The total number of calcium atoms in 80.0 grams of calcium is?
The molar mass of calcium is 40.08 g/mol. To determine the number of moles in 80.0 grams, divide 80.0 g by 40.08 g/mol to get 1.998 moles. Since 1 mole contains 6.022 x 10^23 atoms, the total number of calcium atoms in 80.0 grams is approximately 1.20 x 10^24 atoms.
What is the total number of moles of atoms present in 1 mole of Ca3(PO4)2?
five
What is the total number of atoms in 12.7mol Ca?
12.7 moles calcium (6.022 X 10^23/1 mole Ca) 7.65 X 10^24 atoms of calcium in 12.7 moles.
How many atoms are in 175 g of calcium?
To find the number of atoms in 175 g of calcium, we need to first calculate the number of moles of calcium using its atomic mass (40.08 g/mol). Then, we can use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles to atoms. Finally, multiply the number of moles by Avogadro's number to get the total number of atoms in 175 g of calcium.
How many ions or atoms of calcium and chloride in 1.5 moles of CaCl2?
In 1.5 moles of CaCl2, you would have 3 moles of ions or atoms of calcium and 3 moles of ions of chloride. Since CaCl2 dissociates into 1 calcium ion (Ca2+) and 2 chloride ions (2Cl-), this means you would have 3 moles of calcium ions and 6 moles of chloride ions in total.
What is the total number of atoms in the formula unit for calcium nitride?
The formula unit for calcium nitride is Ca3N2. To find the total number of atoms, you add the number of atoms in each element together: 3 calcium atoms + 2 nitrogen atoms = 5 atoms in total.
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.
What is the total number of atoms in Calcium Chlorate?
The chemical formula for Calcium Chlorate is Ca(ClO3)2. To find the total number of atoms, we add up the atoms in the formula: 1 Calcium atom, 2 Chlorine atoms, and 6 Oxygen atoms, making a total of 9 atoms in Calcium Chlorate.
What is the total number of atoms in a sample of cocaine hydrochloride C17H22ClNO4 of mass 24.5 mg?
To find the total number of atoms in a sample of cocaine hydrochloride, you need to calculate the number of moles using the formula: moles = mass (in grams) / molar mass. Then, you multiply the number of moles by Avogadro's number (6.022 x 10^23) to get the total number of atoms.
What would be the total number of atoms in ten molecules of calcium carbonate?
This number is 50 atoms.
