Answer:B: data verified by other studies
C:data provided by an ice cream manufacturer
E: data provided by an ice cream manufacturer
Concentration (m) signify 'molality'
Concentration (M) signify 'Molarity'
Formula for molality (m) =
In the question denisty of solute is not given so we can calculate concentration (M) that is 'Molarity'
Molarity (M) =
Moles of solute CH3OH = Given grams / Molar mass of CH3OH
Given grams of CH3OH = 12.9 g and molar mass = 32.0 g/mol
Moles of solute CH3OH =
Moles of solute CH3OH = 0.403 mol
Volume of solution = 230 mL , we need to convert 230 mL to 'L'
Volume =
Volume = 0.23 L
Molarity (M) =
Concentration (M) = 1.75 mol / L or 1.75 M

It is lactic acid the chemical is produced during vigorous exercise when the supply of oxygen is limited or inadequate. <span> It forms when the body breaks down carbohydrates to use for energy during times of low oxygen levels. Hope this answers the question. Have a nice day.</span>
In order to attain equilibrium, you need to have a minimum of a minute amount of PH3BCl3(s) left in the flask. Alternatively, it will be all spend before you attain equilibrium concentration. Let PH3BCl3(s) be called C. Molecular weight of C is 151.
4.32x10^-2molC/1L x 0.25 L x 151gC/1molC = 1.63 g C is the answer.
