Answer:
Water waste is produced by a fuel cell.
Explanation:
3.23 x 10²³ atoms
Explanation:
Given parameters:
Volume of Argon atoms = 12L
Condition = STP
Unknown:
Number of atoms = ?
Solution:
We start from the known to the unknown. We know the volume of gas at STP to be 12L;
using the equation below, we can solve for the number of moles and find the amount of atoms.
Number of moles =
Number of moles = = 0.54mole
1 mole of substance contains 6.02 x 10²³ atoms
0.54 mole will contain 6.02 x 10²³ x 0.54 = 3.23 x 10²³ atoms
