Say you need to make a solution of 1M NaCl for a reaction you are running. How would you know how much salt to weigh out and then add to a given volume of water? To do this, you need to find a way to relate the mass of a compound (salt) to the number of moles of that comp...
Instead, it is because K and Cl react in a 1-to-1 molar ratio. A mole consists of 6.02 × 1023 irreducible "pieces" (atoms or molecules) of a substance. Every element's molar mass, or the mass of a single mole in grams is given in the periodic table of elements (see the ...

When thinking about the impact force of a falling object, you can calculate the energy of the object at its point of impact if you know the height from which it was dropped. This type of energy is known as gravitational potential energy and it is equal to the object's mass multiplied by...
So we can calculate the molar concentration of a solute by finding the ratio between the moles of the solute that are contained in the solution per volume of solution: Molarity=mol soluteL ofsolutionAnswer and Explanation: To find the mass of H2SO4, we'll need to find the ...
Typically, the molar mass represents the mass corresponding to the one mole of a chemical solution or mixture. It is usually computed by taking the ratio of mass and mole of a chemical mixture or element. We generally use gram per mole in chemistry to show the molar mass. ...
How to Calculate the Molar Mass More Details on the Calculation Definition The molar mass can be defined as the mass of one mole of any substance. As for a mole, that’s just the overall number of atoms in twelve grams of the carbon-12 isotope. That’s always a fixed number, often ...
take 0.05 ml = 50 ul of stock solution and dilute it with 150 ul of solvent to get the 200 ul of 25 mg/ ml solution needed (remember that the amount of solvent used is based upon the final volume needed, so you have to subtract the starting volume form the final to calculate it....
Calculate the mass of aluminum required to form 18.2 kg of aluminum oxide if the reaction has How many grams of the excess reactant will remain when 31.4 grams of aluminum reacts with 43.5 grams of chlorine? 2Al + 3Cl2 arrow 2AlCl3...
Calculate how many moles of product(s) will be produced if 0.500 mole of H2SO4 were to react completely. 3H2SO4(aq) + 2Fe(s) to Fe2(SO4)3(aq) + 3H2(g) Consider the reaction: 2C_2H_2 + 5O_2 to 4CO_2 + 2H_...
