Hi, the answer is 34.45 , basically 34.
The total pressure of the gaseous mixture has been 5.37 atm. Thus, option D is correct.
The partial pressure has been defined as the pressure exerted by each gas in the mixture.
According to the Dalton's law of partial pressure, the total pressure of gas has been the sum of the partial pressure of the gases in the mixture.
The given partial pressure of gases in the mixture has been:
- Partial pressure of Nitrogen,

- Partial pressure of Oxygen,

- Partial pressure of Argon,

- Partial pressure of Helium,

- Partial pressure of Hydrogen,

The total pressure of the gaseous mixture has been:

The total pressure of the gaseous mixture has been 5.37 atm. Thus, option D is correct.

Answer:
14.61 g NaCl
Explanation:
Molarity = moles / volume of solution (litres)
0.500 = moles / 0.500 L
moles = 0.25
Molar mass of NaCl is 58.44 g NaCl /1 mol NaCl.
0.25 moles NaCl x 58.44 g NaCl /1 mol NaCl
= 14.61 g NaCl
she will have to listen to all of carefully while she is writing for example:
she will listen and look at her writing page (where she writes) she looks while she listens and writes what she hears for example again:
(pretend as i am her.)
"Hey mom, dad, brother come i see crabs!" as she writes it she focuses on how she writes and stops the video and back up again to listen so she can see if it was correct.
