Table salt, also known as sodium chloride or NaCl, for example, exhibits a formula weight of 58.44, which means that 58.44 grams of sodium chloride would represent 1 mole, or 6.022 x 10^23 formula units of NaCl. Advertisement Molar Mass Calculator Common Compounds Periodic Elements Chemical...
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: 2gNaCl(1molNaCl58.44gNaCl)(6.022×1023moleculesNaCl1mol)=2.1×1022moleculesNaCl This ca...
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...
Task:When 150 g of sodium reacted with an excess of chlorine, 381 g of sodium chloride was formed. Find the molar mass of the sodium equivalent, its equivalent, and the number of equivalents in the sample in mol if the molar mass of the chlorine equivalent is 35,5 g/mol. Decision:Fr...
How many grams of NaCl are required to make up 2.00 L of a 4.00 M solution of NaCl ? How many grams of sodium chloride would be required to prepare 3.5 L of a 0.25 M NaCl solution? How many grams of NaCl is needed to prepare a 2.0M NaCl solution? (Molar...
1. Find the Number of Moles of Salt Rounding to one decimal place, the mass of one mole of sodium (Na) is 23.0 grams and that of chlorine (Cl) is 35.5 grams, so one mole of NaCl has a mass of 58.5 grams. You have 12 grams, which equals 12/58.5 = 0.21 moles. ...
Grams to Moles: The mass of a substance (m) in grams can be converted into the moles of the substance (n) with the help of the molar mass of the substance (M) as a conversion factor. n=mM Answer and Explanation: Learn more about this topic: ...
What is the molarity of the HCl solution? Consider the titration below: HCl + NaOH \to NaCl + H_2O If it takes 15.70 mL of 0.117 M of NaOH to reach the equivalence point, determine the molar concentration of HCl. The volume of HCl is 5.00 mL. How do you find the concentration of...
