Kipish [7]3 years ago
4 0

Answer:

Volume of methanol present in solution = less than 3 ml

Explanation:

Given:

Volume of solution = 750 ml

Find:

Volume of methanol present in solution

Computation:

Volume of methanol present in solution = Volume of solution x 0.4%

Volume of methanol present in solution = 750 ml x 0.4%

Volume of methanol present in solution = 3 ml

Volume of methanol present in solution = less than 3 ml

Please help with an easy percentage yield question ASAP!!! Would really appreciate!
Brut [27]

Answer:

The mass percentage yield is 85%

Explanation:

<u>Step 1: </u>The balanced equation

2 C7H6O3 +  (CH3CO)2CO → 2 C9H8O4 + H20

<u>Step 2</u>: Given data

mass of salicylic acid = 1.03 grams

Volume of acetic anhydride = 2.00 mL = 2*10^-3 L

The product is 1.16 g aspirin synthesized

Molar mass of salicylic acid = 138.12 g/mole

Molar mass of aspirin = 180.16 g/mole

Density of acetic anhydride = 1.0820 g/mL

<u>Step 3</u>: Calculated moles of salicylic acid

Number of moles of salicylic acid = mass of salicylic acid / Molar mass of salicylic acid

Number of moles of salicylic acid = 1.03 grams / 138.12 g/mole

Number of moles of salicylic acid =0.0075 moles

Step 4: Calculated mass acetic anhydride

mass of acetic anhydride = 1.0820 g/mL * 2 mL = 2.164 grams

Step 5: Calculate number of moles of acetic anhydride

Number of moles = 2.164 grams / 102.09 g/moles

Number of moles = 0.0212 moles

<u>Step 6</u>: Find amount of reacting moles

C7H6O3 is the limiting reactant, there will react 0.0075 moles

Since for 2 moles C7H6O3 consumed, we need 1 mole of (CH3CO)2CO to produce 2 moles of C9H804

So for 0.0075 moles C7H6O3 consumed, we produce 0.0075 moles of C9H8O4

<u>Step 7</u>: Calculate mass of aspirin

mass of aspirin = 0.0075 moles * 180 g/mole = 1.35 grams

<u>Step 8:</u> Calculate the mass percentage yield

(1.16 grams / 1.35 grams) * 100% = 85 %

The mass percentage yield is 85%

Help me plz plz bbbbb

Answer:

The respiratory system is the network of organs and tissues that help you breathe. basically your airways, lungs, and blood vessels so you quite literally need these to survive I mean your muscles need oxygen to function and your brain needs oxygen to function so without your respiratory system you wouldn't be able to move much and you would quickly pass out and die from the lack of oxygen to your brain there are other body processes that need oxygen as well but these are just two examples.

John and Alex were asked to make a 0.70 M solution. John measure out .35 L from the 2.0 M solution before asking how much soluti
nasty-shy [4]

Answer:

1.0 L

Explanation:

Given data

  • Initial volume (V₁): 0.35 L
  • Initial concentration (C₁): 2.0 M
  • Final volume (V₂): ?
  • Final concentration (C₂): 0.70 M

John and Alex prepared a diluted solution from a concentrated one. We can find the volume of the diluted solution using the dilution rule.

C₁ × V₁ = C₂ × V₂

V₂ = C₁ × V₁ / C₂

V₂ = 2.0 M × 0.35 L / 0.70 M

V₂ = 1.0 L
