How many atoms of calcium are present in 61.5g?
61,5 g calcium contain 9,241.10e23 atoms.
How many moles of oxygen atoms are in 2.53 g of calcium hydroxide?
The answer is 0,068 mol (for O not for O2).
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
How many atoms in 1 gram of calcium?
To find the number of atoms in 1 gram of calcium, you can use Avogadro's number and the molar mass of calcium. The molar mass of calcium is approximately 40.08 grams per mole. Therefore, 1 gram of calcium is about 0.0249 moles (1 g / 40.08 g/mol). Multiplying this by Avogadro's number (approximately (6.022 \times 10^{23}) atoms/mole) gives roughly (1.50 \times 10^{22}) atoms in 1 gram of calcium.
How many atoms are in 163g of calcium?
To find the number of atoms in 163 grams of calcium, first determine the molar mass of calcium, which is approximately 40.08 g/mol. Next, calculate the number of moles in 163 grams by dividing 163 g by 40.08 g/mol, resulting in about 4.06 moles. Finally, multiply the number of moles by Avogadro's number (approximately (6.022 \times 10^{23}) atoms/mol) to find that there are roughly (2.44 \times 10^{24}) atoms in 163 grams of calcium.

There are 6.02 x 10^23 atoms of calcium in 1 gram of calcium.
How many atoms are in 133 g of calcium?
To determine the number of atoms in 133 g of calcium, you first need to calculate the moles of calcium using the molar mass of calcium, which is 40.078 g/mol. Then, you use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles to atoms. This will give you the number of atoms in 133 g of calcium.
How many atoms are in 149 g of calcium?
To calculate the number of atoms in 149 g of calcium, you first need to convert the grams to moles using the molar mass of calcium. The molar mass of Calcium is 40.08 g/mol. Then, you can use Avogadro's number (6.022 x 10^23 atoms/mol) to find the number of atoms in the moles of calcium.
How many atoms are in 173 g of calcium?
To determine the number of atoms in 173 g of calcium, you first calculate the number of moles using the molar mass of calcium (40.08 g/mol). Next, use Avogadro's number (6.022 x 10^23 atoms/mol) to find the number of atoms in the given mass of calcium. The final calculation shows there are approximately 2.71 x 10^24 atoms in 173 g of calcium.
How many atoms are in 141 g of calcium?
The molar mass of calcium is 40.08 g/mol. To find the number of atoms in 141 g of calcium, divide the given mass by the molar mass and then multiply by Avogadro's number (6.022 x 10^23). This will give you approximately 2.12 x 10^23 atoms in 141 g of calcium.
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.
Which has more atoms 10.0 g of oxygen or 10.0 g of calcium?
10.0 g of calcium has more atoms because calcium has a higher atomic mass than oxygen.
How many atoms of calcium are in 1.00 gram?
There are 6.023 x 10^23 atoms in each mole of calcium. I mole of calcium is 40 g, so 1 g contains 6.023 x 10^23/40 atoms = 1.506 x 10^24
How many atoms are in 139 g of calcium?
Amount of Ca = 139/40.1 = 3.47mol 1 mol of Ca contains 6.02 x 1023 atoms (avogadro constant). 3.47mol of Ca thus contains 3.47 x 6.02 x 1023 = 2.09 x 1024 atoms
How many atoms in 133 g of calcium?
