Portion control is controlling the amount of food you eat. It is important because your body needs a certain amount of vitamins and protein.
Answer:
6.3 atm.
Explanation:
Data obtained from the question include:
Initial pressure (P1) = 6 atm
Initial temperature (T1) = 15°C = 15°C + 273 = 288K
Final temperature (T2) = 30°C = 30°C + 273 = 303K
Final pressure (P2) =..?
Since the volume and number of mole of the hydrogen gas sample is constant, the following equation will used to obtain the new pressure:
P1/T1 = P2/T2
6/288 = P2 /303
Cross multiply
288 x P2 = 6 x 303
Divide both side by 288
P2 = (6 x 303) /288
P2 = 6.3 atm
Therefore, the new pressure of the hydrogen gas sample is 6.3 atm.
Answer: heck the chemistry app itll help you i dont know this answer but the app will tell u!
Answer : The final concentration of the seawater is, 2.909 mole/L
Explanation :
Formula used for osmotic pressure :

where,
= osmotic pressure = 70.0 bar = 70 atm
R = solution constant = 0.0821 Latm/moleK
T= temperature of solution = 
C = final concentration of seawater = ?
Now put all the given values in the above formula, we get the concentration of seawater.


Therefore, the final concentration of the seawater is, 2.909 mole/L
