Then, plug the given atomic elements and number of moles to get the mole ratios of water which are the following: {eq}\dfrac{moles \,H}{ moles \,O} = 2\\ \dfrac{moles \,O}{ moles \,H } = \dfrac{1}{2}\\ {/eq}
Chemistry is full of many different confusing conversions. These conversions are important because they ultimately allow us to discover how a particular atom or molecule will interact with other atoms and molecules. Central to chemical conversions is the conversion of grams to moles, and vice versa....

As a result, the plasma "seeks" to return the value of osmolarity to its equilibrium value, which is in the range of 275 to 295 mmol/L in humans. It can do this either by increasing the amount of water in plasma or by excreting the molecules and matter contributing to the increased c...
In stoichiometry, mole ratio is important when analyzing compounds and equation reactions. To analyze compounds, weigh the components and calculate the number of moles of each, using their atomic masses. In reactions you get the mole ratio of the reactan
What is the volume of the liquid in the graduated cylinder read to the proper number of significant figures? How do you use coefficients to balance a chemical equation? How do you read a chemical reaction equation? The following calculation will give the number of molecules in two moles of ...
Imagine trying to get from an opossum to a brown bat in 650 increments. Or from an opossum to a whale. Whales have no pelvis, have flukes, have very weird skulls (especially the sperm whale), have blow holes up top, have temperature control that allows them to swim in arctic waters ...
Sometimes you're given a value inmolesand need to convert it to grams. To do this, first calculate the molar mass of a sample. Then, multiply it by the number of moles to get an answer in grams: grams of sample = (molar mass) x (moles) ...
Answer to: Given a solution in moles per liter, how would you convert to parts per million (ppm)? By signing up, you'll get thousands of...
or the molarity. A mole is a term which stands for 6.02 x 10^23 atoms or molecules of chemical. Another less common unit of concentration is molality. Molaility is the moles chemical per kilogram of solvent used in making the solution. You can convert from molarity to molality if you kno...
