Following the law of conservation of mass, the mass percent of hydrogen in the resulting compound is 14.4%(wt/wt). This is assuming that all of the carbon reacts with all of the hydrogen. The solution is as follows:
mass % = mass hydrogen*100/total mass = 28.8*100/(28.8+171.2) = 14.4%
Given :
Number of moles of CHF₃ is 1.7 .
Solution :
We know, 1 mole of any complex contains 6.022 × 10²³ molecules.
Let, 1.7 moles of CHF₃ contains n numbers of molecules.
So, n = 1.7 × 6.022 × 10²³ molecules
n = 10.2374 × 10²³ molecules
n = 1.0237 × 10²³ molecules
Hence, this is the required solution.
Answer:
Wavelength = 0.06024 m
Explanation:
Equation of energy of wavelength from Einstein's relativity equation is;
E = hc/λ
Where;
h is Planck's constant = 6.626 × 10⁻³⁴ J. s
c is speed of light = 3 × 10⁸
We are given E = 3.3 × 10^(-24) J
Making wavelength λ the subject, we have;
λ = hc/E
Thus;
(6.626 × 10⁻³⁴ × 3 × 10⁸)/(3.3 × 10^(-24)) = 6.024 × 10^(-2) = 0.06024 m
Wavelength = 0.06024 m
