A compound has an empirical formula of C3H10 and a molar mass of 92.26 g/mol. What is its molecular formula?

C6H20

Explanation:

Use this formula to convert emperical to molecular:

Actual mm (molar mass) = n(emperical mm)

Emperical mm:

C3H10= 3(12.01)+10(1.01)=46.04g/mol

Now plug in:

92.26=n(46.04)

n=2.00391

Round it as 2

Then take the n value and multiply it with the subscripts of the emperical formula:

(C3H10)2

C6H20

most historians agree that gabriel mouton, the vicar of st. paul’s church in lyons, france, is the “founding father” of the metric system. he proposed a decimal system of measurement in 1670. mouton based it on the length of one minute of arc of a great circle of the earth (now called a nautical mile, 1852 meters). he also proposed the swing-length of a pendulum with a frequency of one beat per second as the unit of length (about 25 cm). a pendulum beating with this length would have been fairly easy to produce, thus facilitating the widespread distribution of uniform standards. over the years, his work was revised, improved, and extended by a number of french scientists.

the political sponsor of weights and measures reform in the french revolutionary national assembly was the bishop of autun, better known as talleyrand. under his auspices, the french academy appointed several committees to carry out the work of developing a usable system of weights and measures for france. one of the committees recommended a decimalized measurement system based upon a length equal to one ten-millionth of the length of a quadrant of the earth’s meridian (i.e., one ten-millionth of the distance between the equator and the north pole).
