How to Solve General Chemistry Problems is a self-teaching text whichhelps students solve problems found in most general chemistry textbooks. Its sequence of chapters is arranged to coincide closely with the sequence in most popular general chemistry textbooks. The aim is to make it easier for tod...
You pour 12 grams of salt (NaCl) into a beaker containing 20 ounces of water. What is the molarity of salt in the solution? You can solve this problem in three easy steps: 1. Find the Number of Moles of Salt Rounding to one decimal place, the mass of one mole of sodium (Na) is...

density = mass / volume You can rewrite the equation to solve for mass: mass = volume x density Densityof liquids usually is expressed in units of g/ml. If you know the density of a liquid and the volume of the liquid, you can calculate its mass. Similarly, if you know the mass an...

In chemistry, a mole is a quantity used relate reactants to products in stoichiometric equations. A mole of any substance is equal to 6.02 x 10^23 particles -- usually atoms or molecules -- of that substance. For a given element, the mass (in grams) of o
Solve for Tf as follows: Reaction enthalpy = (heat capacity of contents) x (mass of contents) x (Ti – Tf) + (Calorimeter constant) x (Ti – Tf) Factor (Ti – Tf) out of the right side to yield: Reaction enthalpy = (Ti – Tf) x ( (heat capacity of contents) x (mass of ...
