Answer:
128 g/mol
Explanation:
The molar mass is how much a mol of the substance weight.
In this question the weight is given (1.570 g).
To find the number of moles in the sample, we use the ideal gas law: PV=RnT
P= 1atm
V= 577mL= 0.577L
R (universal gas constant)= 0.08206(
)
n= number of moles
T= 300°C= 573.15K
Solving for n:
n= 
<em>k</em>
n=0.0123mol
Molar mass=
Molar mass=128
True I believe because when the current circuit is at its limit it will be damaged
Answer:
Ph-OH
Explanation:
Nitration of Aromatic compounds is an example for Aromatic Electrophilic substitution and its rate is enhanced by Electron donating group like OMe, OH, alkyl group and halides (least activating group) while reactivity is diminished by electron withdrawing like CN,NO2 and Ketone etc
Hence phenol is more reactive than benzene towards nitration.

The shortest distance taken by the object to reach the destination at a minimum time is called acceleration. Thus value acceleration depends upon the displacement and time.
