Calculation mass of substances from Avogadro's constant:The Avogadro's constant means that one mole of a unit substance is made up of {eq}\rm 6.022 \times 10^{23} {/eq} molecules. The calculation of mass from the molecules depends on the moles of a substance in question, which ...
1. What is the molecular mass of methanol? Methanol: Methanol is a chemical compound. This means it is made up of two or more chemical elements that are bonded together. The chemical formula for methanol is CH3OH. This means that in one molecule of methanol, there are 4 atoms of hydroge...
What is the mass concentration (in mg/mL) of glucose, {eq}C_6H_{12}O_6{/eq}, if 18 g of glucose is dissolved in 300 mL of water? Unit Conversion Unit conversion is used when we need to express a measurement from one unit to anot...
When 6.66 g of methane (CH_4) gas, was burned in excess oxygen at 75 degrees C, the internal energy change was -367.2 kJ. Calculate the enthalpy change for the combustion of one mole of methane at 75 degrees C. Using the standard heats of formation, what is...
The methods used in this study include UV and NMR spectroscopy, electrospray ionization-mass spectrometry (ESI-MS), phase-solubility, and molecular modeling. Physicochemical Characterization and Cyclodextrin Complexation of the Anticancer Drug Lapatinib In the ESI-MS or ESI-MS/MS configurations, the ion...
What is the meaning of boiling point in science? Boiling point of CH3OH? What is the melting point of pure water? Which compound has the lowest normal boiling point? What property of water results from its high boiling point? What is the effect of molecular mass on boiling point?
What is the boiling point of isopropanol? Which compound has the lowest normal boiling point? What are the boiling points of the homologous series of alkanes? What is the effect of molecular mass on boiling point? What is the normal boiling point of liquid propanol? What is the normal boilin...
A thermodynamic system is characterized and described by microstates and macrostates. Macrostates represent the physically observable bulk properties of the system like pressure, temperature, volume, etc. Microstates represent the molecular-level propert...
These are much weaker than the chemical bonds but are essential in determining the overall property of the compound. For instance, the fact that water has a higher boiling point than methanol even though methanol has a higher molar mass is explained by the IMFA present....
What is the boiling point of isopropanol? What property of water results from its high boiling point? Which compound has the lowest normal boiling point? What is the effect of molecular mass on boiling point? Boiling point of aluminum? Which chemical element has the highest boiling point? What...
