A gas has density 2.41 g/liter at 25°C and 770 mm Hg. Calculate it's molecular mass (R = 0.0821 L atm. mol-1K-1. ASAP ​

Molecular mass, M = 58.20 g/mol.

Explanation:

Given the following data;

Conversion:

760 mmHg = 1 atm

770 mmHg = 770/760 = 1.0131 atm

Temperature = 25°C = 273 + 25 = 298 K

To find the molecular mass, we would use the ideal gas law equation (density version);

PM = dRT

Where;

Making M the subject of formula, we have;

Substituting into the formula, we have;

Molecular mass, M = 58.20 g/mol.

it would be d. henry moseley

hope this !

and sorry if i'm late. have a good rest of your day! : d
