Question

a sample of vitamin c is known to contain 2.58×10 raised to power 24 oxygen atoms . how many moles of oxygen atom are present in a sample ?

Answer 1

$\textsf{We know that : }$

✿  $\sf{One\;Mole\;of\;Oxygen\;Atoms\;contain : 6.023 \times 10^2^3\;Oxygen\;Atoms}$

$\sf{Given : The\;Sample\;of\;Vitamin\;[C]\;contains\;2.58 \times 10^2^4\;Oxygen\;Atoms}$

$\sf{Number\;of\;Moles\;of\;Oxygen\;Atoms\;in\;the\;given\;Vitamin\;[C]\;Sample :}$

$\sf{\implies \dfrac{(2.58\times 10^2^4)(One\;Mole)}{6.023 \times 10^2^3}}$

$\sf{\implies {(0.428\times 10)\;Moles}$

$\sf{\implies 4.28\;Moles}$
