Mr(C5H11) = 12 x 5 + 1 x 11 = 71 g/mol

R = 142 g/mol / 71 g/mol = 2

C10H22

The molecular formula of a compound used for bleaching hair is h2o2. Calculate (a) mass of this compound that would contain 2.5 moles (b) no.of moles of this compound that would exactly weigh 30g .

a) m(H2O2) = n(H2O2) ∙ M(H2O2) = 2.5 mol ∙ 34 g/mol = 85 g b) n(H2O2) = m(H2O2) / M(H2O2) = 30 g / 34 g/mol = 0.88 mol Answer: a)...

The empirical formula of a compound is CH. At 200 degrees Celsius, 0.242 of this compound occupies 97.2 mL at a pressure of 0.740 atm. What is the molecular formula of the compound

M=mRT/PV=0.242*8.314*(200+273.15)/(0.74*101.325*0.0972)=130(number of CH)=M/M(CH)=130/(12+1)=10Answer: C10H10.

What is the effect of low molecular weight and high molecular weight polymers on crystallinity? Give answer in detail.

The size and structure of the crystals and the degree of crystallinity depend on the type and structure of the polymer, and on the growth conditions. Narrow molecular weight, linear polymer chains, and high molecular weight increase the crystallinity. ......
