Answer:

235L

Explanation:

PV =nRT

V = nRT/P

47.20 °C is 320.35K

V = (79.5 mol)(0.0821 atm•L/mol•K)(320.35K)/8.91atm

V = 234.6698577L

Round to 3 sig figs: 235L

How many molecules are there in 8.25 moles of CaHia?
expeople1 [14]

The number of molecules : 4.967 x 10²⁴

<h3>Further explanation   </h3>

A mole is a number of particles(atoms, molecules, ions)  in a substance

This refers to the atomic total of the 12 gr C-12  which is equal to 6.02.10²³, so 1 mole = 6.02.10²³ particles  

Can be formulated :

N = n x No

N = number of particles

n = mol

No = 6.02.10²³ = Avogadro's number

8.25 moles of C₈H₁₈

The number of molecules :

\tt 8.25\times 6.02\times 10^{23}=4.967\times 10^{24}

Which statement correctly compares electric charge with electric current?
Arisa [49]

Answer:

Your answer would be D) They both require a movement of charged particles

Explanation:

In short terms both the charge and the current are made up of charged particles that are always moving, they constantly move to well... stay charged, if they stopped, then the charge would fade until there is nothing left, and if there is nothing left -it means there would be no electricity to use
