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
