The right answer is 8.74L

The liter is the equivalent of cubic decimetre (dm³).

to convert between cubic units one must multiply or divide by 1000 (and not 10). So 1dm³ equals 1000cm³ (cubic centimeter).

in this exercise we have 8740cm³ (the comma in 8,740 is just to separate each three digits into a number), we have to divide it by 1000 to convert it to dm³.

This gives 8.74dm³ which equals 8.74 liters.

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%

How many molecules are there in 42 grams of AIF3
Sever21 [200]

Answer:

The correct answer is - 3.012×10^23  molecules

Explanation:

The number of molecules is present in any mole of an element or compound are the same. To find the molecules you need to multiply the number of the moles of the compound by Avogadro's number:

Moles are calculated from the molecular weight, for AlF3

= 26.98 + 3×19

= 26.98 + 57

= 83.98

Then moles in 42 grams:

= 42/83.98

= 0.5001190 moles

Now the number of molecules = moles*Avogadro's number

= 0.500110×6.022×10^23

= 3.011×10^23  molecules
