Explanation :
First we have to calculate the mass of blueberries.
As, 1.0 mole of blueberries contains
blueberries
So, 0.75 grams of blueberries contains
blueberries
Mass of blueberries =
Now we have to calculate the number of automobiles needed.
Number of automobiles needed = 
Number of automobiles needed = 
Number of automobiles needed = 
Thus, the number of automobiles needed are, 
Answer:
27°C or 300K
Explanation
We were told that the pressureof the system decreased by 10 times implies that P2= P1/10
Where P2=final pressure
P1= initial pressure
Wew were also told that the volume of the system increased by 5 times this implies that V2= 5×V1
Where T2= final temperature =-123C= 273+(-123C)=150K
T1= initial temperature
But from gas law
PV=nRT
As n and R are constant
P1V1/T1 = P2V2/T2
T1= P1V1T2/P2V2
T1=2×T2
T1=2×150
T1=300K
=300-273
=27°C
the initial temperature (°C) of a system is 27°C
Answer:
Hydration
Explanation:
In water, ions are surrounded by a sphere of water molecules called a hydration shell. The process of forming this shell is called hydration.
