    Answer:

    0.025 moles

    Explanation:

    To find the number of moles in a substance given it’s number of entities we use the formula

    n =  \frac{N}{L} \\

    where n is the number of moles

    N is the number of entities

    L is the Avogadro’s constant which is

    6.02 × 10²³ entities

    We have

    n =  \frac{1.5 \times  {10}^{22} }{6.02 \times  {10}^{23} }  \\  = 0.024916...

    We have the final answer as

    0.025 moles

    Hope this helps you
