the mole fraction of water was plotted. From the graph, tangent lines were drawn with respect to the curve and specified points from which the equation of these tangent lines were known. By getting the y-intercepts at x=0 for the solute and x=1 for thesolvent, the partial molar volume ...
What are the equations for molarity, molality, density, ppm, ppb, mass percent, volume percent, and mole percent?Solution:A solution in the field of chemistry refers to a homogeneous mixture that consists of two or more compounds in specified amounts th...
The obtained results indicated that the performed two-parameter CEoS modification leads to increase the accuracy of the conventional PR EoS and SRK EoS in comparision to original two-parameter CEoS version and also, PT EoS. The average absolute percent deviation of the VTSRK EoS (c-parameter ...
However, compared to the known value of 46.1 g of ethanol, the value measured had a 108% error. Unfortunately, this was a very big percent error and may have been caused by incorrectly measuring the volume of the gas. Using the ideal gas law, the molar mass of a volatile compound was...
NCERT solutions for CBSE and other state boards is a key requirement for students. Doubtnut helps with homework, doubts and solutions to all the questions. It has helped students get under AIR 100 in NEET & IIT JEE. Get PDF and video solutions of IIT-JEE Mains & Advanced previous year pap...
A solution of glucose in water is labelled as10percentw/w, what would be the molality and mole fraction of each component in the solution? If the density of the solution is1.2gmL−1, then what shall be the molarity of the solution?
This represents the time that the gas takes to drop its temperature (or temperature) by 63.2 percent. Based on this experimental procedure, different correlations have been developed to predict the magnitude of the thermal time constant as a function of parameters like the initial temperature and ...
Calculate (a) the molar concentration of the ammonia solution and (b) convert to percent by the mass concentration of ammonia (17.0 arnu), given a How many grams of NH_3 are in 250 ml of a 20% (w/v) ammonia solution? The mola...
The reproducibility is generally measured by the % CV, which is defined as the standard deviation divided by the mean of the assay result expressed as a percent [65]. The FDA and European Medicines Agency (EMA) ac- ceptance criteria for biological assays typically define the required between-...
What is the mole percent O_2 in the mixture? A mixture of gases containing 21.0 grams of N2, 106.5 grams of Cl2, and 12.0 grams of He at 14 degrees Celsius is in a 50.0 L container. What is the partial pressure ...
