A258-ml sample of mek, an industrial solvent, is found to have a mass of 0.599 g at and 100c. what is the molar mass of mek?

The ans is 71.1 g/mol

Explanation:

Mass of MEK (m) = 0.599 g

Volume of MEK (V) = 258 ml = 0.258 L

Temperature (T) = 100 C = 100 +273 = 373 K

Pressure = 1 atm

Based on the ideal gas equation:

where n = number of moles and R = gas constant 0.0821 Latm/mol-K

number of moles is given as:

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.

if it's not useful, feel free to report for mistake in answer.

you gotta add the following molecules so we can give u an answer
