6. In addition to chains, carbon atoms can bond together to form rings and other shapes. Draw a hydrocarbon that is made up of six carbon atoms, all with single bonds, that forms a ring. Pls i need help

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.

the formula mass of a molecule or a compound is the sum of the atomic weights of the atoms in its empirical formula

(that's what i know about formula mass)
