Question

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

Answer 1

Explanation:

Actual mass of an element = atomic mass of an element in amu x 1.66 x 10 -24 gm. Actual mass of hydrogen atom = 1.008 x 1.66 x 10 -24 gm. = 1.6736 x 10-24 gm. Actual mass of oxygen atom = 16.00 x 1.66 x 10 -24 gm.

Answer 2

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

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

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

• Mass Of One Oxygen Atom

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

We can Conclude that,

$\boxed{\sf\green{★ Mass \: Of \: 1 \: Atom \: Of \: Oxygen = \frac{Strong} {Weight} }}$

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,

$\sf{Mass\:Of\:1\:Oxygen\:Atom\:Is$

$\dagger\textbf\color{green}{2.66 × 10²³Kg.}$
