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 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 are in 147 g of calcium?
The molar mass of calcium is 40.08 g/mol. To calculate the number of atoms in 147 g of calcium, you first need to convert grams to moles, then use Avogadro's number (6.022 x 10^23 atoms/mol) to find the number of atoms. The calculation would be: 147 g / 40.08 g/mol = 3.67 mol * 6.022 x 10^23 atoms/mol = 2.21 x 10^24 atoms.
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 do you find out how many atoms are present in calcium?
To find out how many atoms are present in calcium, you would need to use Avogadro's number, which is 6.022 x 10^23 atoms/mol. Simply divide the mass of the calcium sample by the atomic mass of calcium (40.08 g/mol) and then multiply by Avogadro's number to determine the number of atoms present.
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 of calcium are present in 61.5g?
61,5 g calcium contain 9,241.10e23 atoms.
How many atoms of calcium are in 1.00 g?
There are 6.02 x 10^23 atoms of calcium in 1 gram 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 are in 159g of calcium?
To find the number of atoms in 159g of calcium, you need to first calculate the number of moles of calcium present using the molar mass of calcium. The molar mass of calcium is approximately 40 g/mol. Then, you can use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles of calcium to atoms. Calculate the number of moles of calcium in 159g using the formula: moles = mass (g) / molar mass (g/mol). Finally, multiply the number of moles by Avogadro's number to determine the number of atoms in 159g of calcium.
