Question

Calculate mass of one oxygen atom in terms of amu.( avogadros no.2.656x10

Answer 1

$\large{\underline{\sf{\orange{Points \: To \: Be \: Remembered-}}}}$

• $\large{\boxed{\sf{Atomic \: weight \: of \: oxygen = 16g/mole}}}$

• $\large{\boxed{\sf{1 \: mole \: of \: Oxygen = 6.023 \times {10}^{23} }}}$

$\large{\underline{\sf{\purple{To \: Find-}}}}$

• Mass Of One Oxygen Atom.

$\large{\underline{\sf{\blue{Solution-}}}}$

We can Conclude that,

$\boxed{\sf\green{★ Mass \: Of \: 1 \: Atom \: Of \: Oxygen = \frac{</strong><strong>A</strong><strong>tomic \: </strong><strong>W</strong><strong>eight \: </strong><strong>O</strong><strong>f \: </strong><strong>O</strong><strong>xygen}{1 \: </strong><strong>M</strong><strong>ole \: </strong><strong>O</strong><strong>f \: </strong><strong>O</strong><strong>xygen} }}$

Placing Values,

$\sf\leadsto{ \frac{16}{6.023 \times {10}^{23} } }$

$\sf\leadsto{\frac{\cancel{16}}{\cancel{6.023 \times {10}^{23} }}}$

$\boxed{\leadsto\sf\red{★ \: 2.66 \times {10}^{23} kg}}$

Hence,

• Mass Of 1 Oxygen Atom Is 2.66 × 10²³Kg.
