To figure this out, you will need the molar mass of NaCl which is 58.44 g/mol. First, convert the grams to moles using the molar mass and then use Avogadro's number to find the number of molecules: \(\mathrm{2g\enspace NaCl\Biggl(\dfrac{1mol\enspace NaCl}{58.44g\enspace NaCl}\...
How do you do mass to mole stoichiometry? How is fire a chemical reaction? How do you figure out products of chemical reactions? How do you balance synthesis reactions? What is mass ratio in chemistry? How are chemical equations balanced?
When solid dissolves in a solvent to create a solution, the concentration of the solution can be expressed in a variety of ways. This relates to the fact that chemicals react with each other not on the basis of mass but on the basis of the ratio of individual "pieces," regardless of si...
In chemistry, the mole is used for working with large numbers of atoms. Specifically, 1 mole of a substance contains 6.022×1023 atoms of the substance. This number is also known as Avogadro's constant.Answer and Explanation: In order to find the moles of atoms present in 4.63×1021 Ca ...
Aluminum alloys play an important role in circular metallurgy due to their good recyclability and 95% energy gain when made from scrap. Their low density and high strength translate linearly to lower greenhouse gas emissions in transportation, and their
mean, but in a very early set of problems they ask us to predict how certain reactants would pair up or change in the products. And I could figure out mostly how the reactants would pair up, but really had no idea if it would be a gas, liquid, or solid. Is that still to ...
Based on this information, part (d) asks us tofigure out the molarity of the propanoic acid. First,how many moles of NaOH were put into the solution?We can find this by multiplying the total volume of NaOH solution by its molarity: ...
with tomboy style or have no interest in what is called “feminine”, you still can learn how to present the exclusive charm of a woman without ostentation too much. Here are some simple tips on how to be more feminine you should learn to get better attractiveness from the inside out. ...
Multiply the result from the previous step by the molarity of the acid you used to titrate to figure out how many moles of acid you used. Recall that in our example we titrated with 1 M acid. Example: 0.002 x 1 = 0.002 moles
To do this, you need to find a way to relate the mass of a compound (salt) to the number of moles of that compound. The molar mass of elements tells you the molar mass of a compound, so you can figure this out. Molar Mass Definition ...
