The density of titanium metal is 4.51g/cm3 at 25 degrees celsius. What mass of titanium displaces 125.0mL of water at 25 degrees celsius?
Compute the a)molarity of the solution, b)molality of the solution, c) mole fraction of Ammonia.
Identifying and balancing the different types of chemical reactions. Evaluate which processes represent chemical reactions.
A multiple stage evaporate process concentrates a weak solution of LiOH from 4.48 wt% to 26.78wt%. This evaporator processes 10 metric tonnes of solution each day.
A student is concentrating a solution having a polypeptide of modest molecular weight by pressure filtration through a membrane. The solute concentration on the feed side of the membrane is 0.10 M and the temperature is twenty five degree celsius.
determines how many grams of glucose are in 100 mL of the final solution?
determine how many grams of C 12 H 22 O 11 (sucrose) (mm = 342 g/mol) does he need if he uses 375 grams of Water? it is given that the vapor pressure of water =17.5 mm Hg. at 20 degree celsius temperature)
If iron is oxidized to Fe2+ by a copper(II) sulfate solution, and 0.434 grams of iron and 12.2 mL of 0.52M copper(II) sulfate react to form as much product as possible.
Using a sample of ferrous ammonium sulfate hexahydrate of 0.5585 grams needs KMnO 4 solution of 21.45 ml to reach a pink endpoint then calculate what will be tha molarity of the KMnO 4 solution?
In an experiment for measuring water hardness in a water sample, using Atomic Absorption Spectrophotometry, I obtained a value of 173.74 ppm hardness for my water sample.
Hardness in groundwater is due to the presence of metal ions, primarily Mg2+ and Ca2+. Hardness is generally reported as ppm CaCO3 or mmol/L Ca2+.
The reaction between white phosphorous and oxygen produces solid tetra phosphorus decoxide (P 4 O 10 ).
Calculate the pressure when temperature is increased to 383 0C and volume of container keeps constant?
