What is scientific meaning for emerge?
cluponka [151]
When we're talking about something that's emerging, we're talking about a characteristic of a certain object we're observing which couldn't be directly inferred from its known constitutional parts. 

If we know water is made out of oxygen and two hydrogen molecules, we cannot predict certain qualities it has. What we need to know and what is important is that we also know the interaction between the constitutional parts of our object so that we can properly explain the new observed characteristic.

What is the pressure in atm exerted by 2.48 moles of a gas in a 250.0 mL container at 58 degrees celsius
Dvinal [7]
Since the question manages to include moles, pressure, volume, and temperature, then it is evident that in order to find the answer we will have to use the Ideal Gas Equation:  PV = nRT (where P = pressure; V = volume; n = number of moles; R = the Universal Constant [0.082 L·atm/mol·K]; and temperature.

First, in order to work out the questions, there is a need to convert the volume to Litres and the temperature to Kelvin based on the equation:
         250 mL = 0.250 L
             58 °C = 331 K

Also, based on the equation   P = nRT ÷ V

⇒         P  = (2.48 mol)(0.082 L · atm/mol · K)(331 K)  ÷  0.250 L
⇒         P  =  (67.31  L · atm) ÷ 0.250 L
⇒         P  =  269.25 atm

Thus the pressure exerted by the gas in the container is  269.25 atm.
