How many moles of platinum are equivalent to 1.20 x 10^24?

Question:

How many moles of platinum are equivalent to 1.20 {eq}\times {/eq} 10{eq}^{24} {/eq}?

Mole (mol):

A mole is a unit of measurement in chemistry. It measures the number of particles (such as protons, molecules, and protons) that are available in a given chemical compound. 1 mole of a chemical compound is equal to {eq}6.022\times 10^{23}{/eq} particles (protons, molecules or protons).

Answer and Explanation:


1 mole of platinum will be equal to {eq}6.023\times 10^{23}{/eq}. Therefore, 1.20 {eq}\times {/eq} {eq}1.20\times 10^{24}{/eq} is equivalent to:

  • {eq}\dfrac{1.20\times 10^{24}}{6.023\times 10^{23}} = \boxed{1.992\, moles}{/eq} of platinum.
