Question

the mass of an atom of oxygen is 16.00u. What is the mass of 18 atoms of oxygen?​

Answer 1

➢$\displaystyle \sf \red{\int \limits^{ \frac{ \pi}{2} }_{0} \frac{3 \sqrt{ \cos \theta} }{( \sqrt{cos \theta} + \sqrt{sin \: \theta}) {}^{5} } \: d \theta}$

Answer 2

Answer:

Given:

Mass of oxygen atom  =16μ

1μ = 1.66×10−27kg

Mass of 16μ 

 =16×1.66×10−27

 =2.656×10−26kg
