What is the relationship between the molecular mass and the molar mass of a substance?
2 answers:
Answer:
The molar mass of a substance is the mass (in grams per mole) of 6.022 x atoms, molecules, or formula units of that substance.
Explanation:
In each case, the number of grams in 1 mol is the same as the number of atomic mass units that describe the atomic mass, the molecular mass, or the formula mass, respectively.

Answer: The pressure 12.2 psi is expressed in millimeters of mercury (mm Hg) as 630.9221 mm Hg.
Explanation:
Given: Pressure = 12.2 psi
According to the standard conversion of units, 14.7 psi = 1 atm = 760mmHg.
Therefore, 1 psi equal to how many mm Hg is calculated as follows.
Hence, 12.2 psi will be converted into mm Hg as follows.
Thus, we can conclude that the pressure 12.2 psi is expressed in millimeters of mercury (mm Hg) as 630.9221 mm Hg.
