What is the molar mass of babr2? a. 217.2 g/mol b. 297.1 g/mol c. 354.5 g/mol d. 434.4 g/mol

Answer : The molar mass of is 297.1 g/mol

Explanation :

Molar mass : It is defined as the sum of the mass of all the atoms each multiplied its atomic masses that are present in the molecular formula of a compound. It is expressed in g/mol.

As we know that,

Molar mass of Ba = 137.3 g/mole

Molar mass of Br = 79.9 g/mole

Now we have to calculate the molar mass of

Molar mass of =

Therefore, the molar mass of is 297.1 g/mol

altitude, density, pressure

air gets less dense the higher the altitude and also the air pressure is less as altitude rises.

the answer is 1 i believe
