Question: How many moles of water are there in 1.000 l at stp? Assume the density of water is 1000 kg/m3? Stoichiometry: Stoichiometry is the branch of chemistry which deals with the measurement of chemical substances in a chemical reaction. This measurement is...
A container has a volume of 53.9 L. Assuming it is at STP, how many moles of gas particles does it contain?Ideal Gas EquationAn ideal gas is gas which fulfill the following condition's 1 Size of the atoms or molecule is negligible as compared ...
Equivalents per liter is therefore a unit of concentration, but the most commonly seen unit throughout chemistry is the mEq/L.Examples of mEq/L 1. How many mEq of potassium are there in 750 mL of solution that has a K+ concentration of 58.65 mg/L? (Note: The molar mass of potassium...
But the units are no longer moles/L, but rather millimoles/L or mmol/L. These units are called millimolar or mM. While in many cases scientists prefer to talk about concentration in terms of molarity, it can sometimes be more useful to talk about mass per liter solvent. For example, ...

Answer to: Concentrated hydrochloric acid has a concentration of 12.1 moles per liter. How many milliliters of the concentrated acid should be used...
What quantity serves as the conversion factor between the mass of a sample and how many moles the sample contains?Unit Conversion:In a unit conversion, we use conversion factors to cancel the units that are not required in the final value and/or ...
meaning that system has either lower or higher barometric pressure than the surrounding areas. Many barometers use mercury to measure barometric pressure. Since the chemical symbol for mercury is Hg, readings of barometric pressure are often reported in inches of mercury (in/Hg) or millimeters of ...
