Answer:
what time you thinking. about coming down to take a break and ok I will get to?. that was a right answer?
La masa molar de 65 litros de SO2 es igual a 64,1 g/mol.
<h3>Masa molar</h3>
La masa molar de un compuesto depende de su masa presente en 1 mol, entonces:

Para calcular la masa molar de un compuesto, simplemente suma las masas de cada elemento en el compuesto, así:


Así, la masa molar de 65 litros de SO2 es igual a 64,1 g/mol.

Answer:
2.295 eV
Explanation:
maximum wavelength, λ = 542 nm = 542 x 10^-9 m
The work function of the metal is defined as the minimum amount of energy falling on the metal so that the photo electrons just ejects the surface of metal.

where, h is the Plank's constant and c be the speed of light
h = 6.634 x 10^-34 Js
c = 3 x 10^8 m/s


Wo = 2.295 eV
Thus, the work function of this metal is 2.295 eV.
Thank you for posting your question here at brainly. Below is the solution:
Ke up top = 1/2*.25 *225
<span>gain of Pot energy = .25*9.81*1.2 </span>
<span>work input = (1/4)(2 pi *.6)*30 </span>
<span>so </span>
<span>sum of those 3 energies = </span>
<span>(1/2)(.25)v^2</span>
