When 1.570 grams of the compound is vaporizedar 300 degrees celius and 1 atmosphere, the gas occupies a volume of 577 milliliters. what is the molar mass of the compound based on the result?

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= k

n=0.0123mol

Molar mass=

Molar mass=128

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.
