URGENT** If you have 35.0g of Na and 100.0g of Cl2, what is the maximum amount of NaCl that you can produce?
Ilya [14]

Answer:

165 g of NaCl are formed in the reaction

Explanation:

2Na + Cl₂ → NaCl

In order to determine the limiting reactant, we convert the mass of each reactant to moles

35 g / 23g/mol = 1.52 moles Na

100 g / 70.9 g/mol = 1.41 moles Cl₂

1 mol of chlorine reacts with 2 moles of Na, so If I have an x value of moles of Cl₂ I would need the double to react.

For 1.41 moles of Cl₂, I need 2.82 moles of Na; therefore my limiting reagent is the Na. Ratio is 2:2. So if I have 2.82 moles of Na I will produce 2.82 moles of NaCl

We convert the moles to mass: 2.82 mol . 58.45 g/1 mol =164.8 g

1. You are asked to make 200 mls of a 20mM working (diluted) solution of NaCl using a 2M stock solution. Record the volume of 2M
vekshin1

Answer:

The volume of 2M stock solution added = 2 mL

The volume of water = 198 mL

Explanation:

Considering

Molarity_{working\ solution}\times Volume_{working\ solution}=Molarity_{stock\ solution}\times Volume_{stock\ solution}

Given  that:

Molarity_{working\ solution}=20\ mM=0.02\ M

Volume_{working\ solution}=200\ mL

Volume_{stock\ solution}=?

Molarity_{stock\ solution}=2\ M

So,  

0.02\ M\times 200\ mL=2\ M\times Volume_{stock\ solution}

Volume_{stock\ solution}=\frac{0.02\times 200}{2}\ mL=2\ mL

<u>The volume of 2M stock solution added = 2 mL</u>

<u>The volume of water = 200 - 2 mL = 198 mL</u>
