chemists use the mole which is equal to {eq}6.02 \times 10^{23} {/eq} atoms. In the laboratory, chemists will weigh substances using grams. The molar mass or molecular weight of a substance is used to determine how many grams per mole of a substance is needed in a ...
A solution is made by mixing 308g of sucrose (a sugar) in 500mL of water. What is the concentration of the solution in mol/L? How many molecules of sucrose are in solution? The molecular mass of sucrose is 342.3 grams per mole. ...
After 24h at room temperature, the distribution of apparent micellar protein mass (M Prot , grams of protein per mole micelles) was determined by sedimentation field flow fractionation. The values of apparent micellar protein mass at the maximum of the micelle peak were in the range 10 9 to ...
The molecular mass of sucrose is 342.3 grams per mole. What mass of sucrose, C_12H_22O_11 is present in 75.0 mL of a 2.50 M solution? A 50.0 mL sample of a 0.250 M sucrose solution was diluted to 5.00 \times 10^2 mL. What is the molar concentration of the resulting solution? Wh...
How many grams of sucrose (C_{12}H_{22}O_{11}) must be dissolved in 60 g water to make a solution in which the mole fraction of sucrose is 0.2? Give your answer in units of g. What is the molality of a solution of sucrose (molar mass = 342)...
there may be used from 0.1 to 5.0 parts by weight of flocculant per million parts by weight of melt sugar solids throughput in the refinery and the flocculant may be added to the aerated mixture in the form of an aqueous solution having a concentration of from 0.25 to 5.0 grams per litre...
All molecular weights as used herein are weight average molecular weights expressed as grams/mole, unless otherwise specified. The term “charge density”, as used herein, refers to the ratio of the number of positive charges on a polymer to the molecular weight of said polymer. Herein, “com...
When the organotin-based acylation promoter is a dinuclear species containing two atoms of tin per molecule (e.g. a distannoxane), it is preferably present in from 0.5 to 2.5 molar equivalents (per mole of sucrose), more preferably from 0.75 to 1.2 molar equivalents, still more preferably ...
there may be used from 0.1 to 5.0 parts by weight of flocculant per million parts by weight of melt sugar solids throughput in the refinery and the flocculant may be added to the aerated mixture in the form of an aqueous solution having a concentration of from 0.25 to 5.0 grams per litre...
