What conversion factor is present in almost all stoichiometry calculations?
Molarity
How do you find molarity with mL?
You convert the mL to liters and use the equation: M=moles/L Using that you should be able to get the molarity....
How many milliliters of 0.248M HCl are needed to react with 1.36 grams of zinc to produce hydrogen?
First, write a balanced equation for this reaction. The reactants are HCl and Zn and the products are ZnCl2(aq), and H2(g). For how to write a balanced equation, see the Related Questions to the left. Then, convert the grams of Zn into moles of Zn. To do that, see the Related Questions to the left. Then use stoichiometry to determine how many moles of HCl are necessary to react with that number of moles of Zn. See the Related Questions to the left for how to solve stoichiometry problems. Finally, determine how many milliliters of solution you need to get that many moles of HCl. To do that, use this equation: number of moles = number of liters * molarity
What is one advantage of percentage over molarity as a measure of solute concentration?
Concentrations in molality (moles of solute per kilograms of solvent) are independent of temperature and pressure whereas concentrations in molarity (moles of solute per total volume of solution in liters) are not.
Why you use titration?
Titration is used to calculate the molarity of an acid or base (standardising), using a base or an acid respectively with a known molarity (primary standard).
What conversion factor is present in almost all stoichiometry calculations?
Molarity
Why are different masses of each element required to react with the same amount of hydrogen?
Each element has a different molar mass and Molarity, using stoichiometry the conversion of molar mass can explain why.

What are the two kinds of stoichiometry?
Stoichiometry is the calculation of the various products and reactants in chemical reactions. The two types are reaction stoichiometry and composition stoichiometry.
How can you identify a stoichiometry problem?
When a problem has a label "stoichiometry" on top of it.
What is an example of stoichiometry?
An example of stoichiometry is any chemical reaction. HCl+NaOH->NaCl+H2O may be an example of stoichiometry.
What is the molarity of pure liquid benzene?
Molarity is a concentration unit of solutions, pure benzene is not a solution so this term is meaningless for a pure liquid. In other words: Molarity of a solution is a numerical way of saying exactly how much solute is dissolved in a solvent .Molarity is equal to the moles of solute divided by the liters of solution. Molarity of a solution can be calculated by using the following formula: M= moles of solute/liters of solution
What is the molarity of the following solution 1.0 moles of KCl in 500mL of solution?
You need to bring this to a litre. If there is 1 mole in 500ml (using ratio), there will be 2 moles in a litre. So your molarity is 2.
How do you measure with a stoichiometry?
Stoichiometry is not a method of measurement, it is a concept for the ratios of reactants and products.
