To determine the number of moles of platinum equivalent to 1.20 x 10^24, we need to use Avogadro's number.
Avogadro's number (NA) is approximately 6.022 x 10^23, and it represents the number of particles (atoms, molecules, or ions) present in one mole of a substance.
To find the number of moles, we can use the following equation:
Number of moles = Number of particles / Avogadro's number
Plugging in the values, we have:
Number of moles = 1.20 x 10^24 / 6.022 x 10^23
Dividing these values, we get:
Number of moles ≈ 1.99
Therefore, 1.20 x 10^24 particles are equivalent to approximately 1.99 moles of platinum.
To find out how many moles of platinum are equivalent to 1.20 x 10^24 platinum atoms, we need to use Avogadro's number.
1 mole of any substance contains 6.022 x 10^23 entities (atoms, molecules, or ions). This value is known as Avogadro's number.
To find the number of moles, we can use the following formula:
Number of moles = Number of entities / Avogadro's number
Let's plug in the given values:
Number of moles = 1.20 x 10^24 atoms / 6.022 x 10^23 atoms/mol
Calculating this division gives us:
Number of moles = 1.994 x 10
^1
0
Therefore, 1.20 x 10
^24
platinum atoms are equivalent to 1.994 x 10
