A 16 gram sample of O2(g) fills a container at STP.<br> What volume is the container?
sergij07 [2.7K]

Answer:

V = 11.2 L

Explanation:

Hello there!

In this case, according to the ideal gas equation:

PV=nRT

It is possible to compute the volume as shown below:

V=\frac{nRT}{P}

Whereas the moles are computed are computed given the mass and molar mass of oxygen:

n=16g*\frac{1mol}{32g} =0.5mol

Now, since the STP stands for a temperature of 273.15 K and a pressure of 1 atm, the resulting volume is:

V=\frac{0.5mol*0.08206\frac{atm*L}{mol*K}*273.15K}{1atm}\\\\V=11.2L

Best regards!

How can you calculate the energy of an electron who moved from E1 to E5?
puteri [66]

Answer:

See explanation

Explanation:

If the energy of the ground state E1 is known, then we need to measure the difference in energy between the energy levels E5 .and E1. We can obtain this by measuring the frequency or wavelength of a photon that is emitted when an electron moves from energy level E5 to E1.

From Bohr's model;

ΔE = E5 - E1

Hence;

E5 = ΔE + E1
