In the solvent pair experiment that is being carried out with the solid that is being recrystallized, why do you not have to wor
kumpel [21]

You do not have to worry  because it will not affect the yield of the pure crystals.

<h3>What is re-crystallization?</h3>

Re-crystallization is the process of obtaining pure crystals from a super saturated solution.

This is done by heating a solution of the impure substance to a high temperature and then allowing the hot solution to cool down and the crystals begin to appear.

You do not have to worry about sudden vigorous boiling of crystal solution when you add the second solvent to the solution because it will not affect the yield of the pure crystals.

kolezko [41]
Answer:
A 12.630 bar of chocolate contains 8315 milligrams of sugar

Explanation:
From the basics of conversion, we can find that:
1 gram is equal to 1000 mg
Using cross multiplication, we can find how many milligrams are present in 8.315 grams as follows:
1 gram .............> 1000 mg
8.315 grams ....> ?? mg
amount in milligrams = (8.315*1000) / 1 = 8315 milligrams

Hope this helps :)

What is the final pressure (expressed in atm) of a 3.05 L system initially at 724 mm Hg and 298 K, that is compressed to a final
maksim [4K]

Hey there!:

V1 = 3.05 L

V2 = 3.00 L

P1 = 724 mmHg

P2 = to be calculated

T1 = 298 K

T2 = 273 K

Therefore:

P1*V1  / T1  = P2*V2 / T2

P2 = ( P1*V1 / T1  )   * T2 / V2

P2 = 724 * 3.05 * 273 / 298 * 3.00

P2 = 602838.6 / 894

P2 = 674.31 mmHg

1 atm ----------- 760 mmHg

atm ------------- 674.31 mHg

= 674.31 * 1 / 760

= 0.887 atm

Hope this helps!
