Question

How many atoms are there in 0.0255 moles of calcium?​

Answer 1

To find the number of atoms in 0.0255 moles of calcium, you can use Avogadro's number. The calculation would be 0.0255 moles x (6.022 x 10^23 atoms/mole) = 1.537 x 10^22 atoms of calcium.

Step-by-step explanation:

To calculate the number of atoms in 0.0255 moles of calcium, you can use Avogadro's number, which states that there are 6.022 x 10^23 atoms in one mole of any substance.

So, to find the number of atoms in 0.0255 moles of calcium, you can calculate:

0.0255 moles x (6.022 x 10^23 atoms/mole) = 1.537 x 10^22 atoms of calcium

Answer 2

Multiply the moles by Avogadro's number (
`6.02` x
`10^(23)`) to get the number of atoms

`(0.0255 \ mol)` *
`(6.02 \ * \ 10^(23))`

= 1.5351 x
`10^(22)`

Therefore the answer is 1.5351 x 10^22 atoms in 0.0255 moles of Calcium
