A sample of C3H8 has 3.28 × 1024 H atoms. How many carbon atoms does the sample contain? What is the total mass of the sample in
sammy [17]
To find the number of carbon atoms, we <span>multiply </span>the 3.28x10^24 by the ratio, 3/8. The total number of carbon atoms is 1.23 x 10^24 atoms. The total mass of the sample is each number of atoms divided by avogadro's number and multiplied by the molar mass of each. The total mass is 29.96 grams.

Is the following compound symmetrical going across?
Nataliya [291]

Answer:

Yes

Explanation:

A molecule has a center of symmetry when, for any atom in the molecule, an identical atom exists diametrically opposite this center an equal distance from it(Wikipedia).

A center of symmetry is said to exist in a molecule when reflection of all parts of the molecule through the center of symmetry produces an indistinguishable configuration(Housecroeft and Sharpe,2012)

Obviously, the Cl2 molecule has a center of symmetry, hence it is symmetrical. Reflection of the molecules through its center of symmetry produces an indistinguishable configuration.
