The allowable concentration level of vinyl chloride, C2H3Cl, in the atmosphere in a chemical plant is 2.0 x 10-6 g/L. a. How many moles of vinyl chloride in each liter does this represent?

3.2x10⁻⁸ moles of vinyl chloride per liter

Explanation:

The concentration of C₂H₃Cl is 2.0x10⁻⁶g/L. To find moles per liter we need to convert this mass to moles using molar mass of vinyl chloride:

Molar mass C₂H₃Cl:

2C = 2*12g/mol = 24

3H = 3*1g/mol = 3

Cl = 1*35g/mol = 35

Molar mass = 35g/mol + 3g/mol + 24g/mol = 62g/mol

2.0x10⁻⁶g * (1mol / 62g) =

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
