How many grams of Cl2 are needed to make 117 grams NaCl?

71.0 grams Cl2. You start out with 117 grams of NaCl and use the mole ratios in the chemical equation, along with unit analysis, to find the grams of Cl2 needed.

How many grams of NaCl are required?

A 1 M solution of NaCl contains 1 mole of NaCl. Na has an atomic mass of 22.99 while Cl has an atomic mass of 35.45, for a formula mass of 58.44 gm/mole. 100 ml. is 1/10 of a liter, so this much solution would require 5.84 grams of NaCl. Therefore, 11.7 g of NaCl is required to make 100 ml of 2M solution of NaCl.

What is the formula for a chlorine molecule?

Formula and structure: the chemical structure of chlorine gas is Cl2 and its molecular weight is 70 g/mol. Its structure is Cl-Cl, which is also called the element form of the chlorine element, consist in 2 atoms of chlorine joined by a covalent bond.

How do you convert the measured mass of a substance to moles?

A substance’s molar mass is calculated by multiplying its relative atomic mass by the molar mass constant (1 g/mol). The molar mass constant can be used to convert mass to moles. By multiplying a given mass by the molar mass, the amount of moles of the substance can be calculated.

How many grams are in 1.70 moles of KMnO4?

269g
1.70 moles KMnO4 = 269g KMnO4 (molar mass KMnO4 = 158.0g)

How do you calculate the number of moles?

Number Of Moles Formula

  1. The formula for the number of moles formula is expressed as.
  2. Given.
  3. Number of moles formula is.
  4. Number of moles = Mass of substance / Mass of one mole.
  5. Number of moles = 95 / 86.94.

How many grams of NaCl are in a 200ml solution?

10 grams
Hence 10 grams of NaCl is required to make 200 mL aqueous solution of 5\%(w/v) NaCl. Note: The mass of solute must always be expressed in grams (g) and the volume of the solution (solvent + solute) should be in milliliters (mL).

How many moles is 24g of NaCl?

Assuming for this example that there are 24g of NaCl, the conversion would be: 24/58.5=. 41 moles of solute.

How do you make chlorine?

Chlorine can be manufactured by the electrolysis of a sodium chloride solution (brine), which is known as the Chloralkali process. The production of chlorine results in the co-products caustic soda (sodium hydroxide, NaOH) and hydrogen gas (H2). These two products, as well as chlorine itself, are highly reactive.

How much NaCl can be produced from 346g of Na and Cl2?

So 346 g of Cl2 produces less NaCl than 500. g of Na, so Cl2 is the limiting reactant, and therefore it limits the amount of NaCl that can be produced. Calculate the mass of NaCl that can be produced by 346 g of Cl2. If 500. g of Na and 346 g of Cl2 react, ~570. g of NaCl can be produced.

What type of reaction is NaCl 2NaCl?

READ:   Can I use sincerely in an email to professor?

What type of reaction is 2NaCl? An example of a synthesis reaction is the combination of sodium (Na ) and chlorine (Cl) to produce sodium chloride (NaCl). This reaction is represented by the chemical equation: 2Na + Cl2 ! 2NaCl Sodium is a highly reactive metal, and chlorine is a poisonous gas (see Figure 8.6).

How much NaCl can be made from one mole of nai/cl2?

Whichever is the least amount possible, then that reagent is the one we ran out of first….it is limiting, and it’ll tell us how much can be made. Everything has to be done in moles. With the Cl2, we can make 0.1410 moles NaCl. Using the NaI, we can only make 0.0333 moles of NaCl.

How do you find the molar mass of NaCl?

The molar mass of NaCl is 58.44 g/mol NaCl. Determine the moles of Na that reacted. Multiply mol NaCl by multiplying mol NaCl by the mol ratio between NaCl and Na from the balanced equation, so that mol NaCl is cancelled. Determine the mass of Na that reacted. Multiply mol Na by its molar mass.
