Assuming that 1.0g of aspirin dissolves in 450 mL of water at 10o C, how much aspirin would be lost in the 1.4 mL of water added

to the reaction mixture if the mixture were at 10o C during the filtration? Would this significantly affect the percent yield above?

Answer:

amount of aspirin dissolved = 0.0031 g

so we can say that this is not affect % yield as amount of aspirin lost is very less

Explanation:

given data

mass of aspirin = 1 g

volume of water = 450 mL

solubility of aspirin temperature = 10° C

volume of water added = 1.4 mL

to find out

how much amount aspirin would be lost

solution

we know the solubility of aspirin is

solubility of aspirin = \frac{mass\ of\ aspirin}{volume\ of\ water}

solubility of aspirin =  \frac{1\ g}{450\ mL}  

solubility of aspirin = 2.2 × 10^{-3} g/mL

so

we can say

amount of aspirin dissolved =  solubility of aspirin × volume of water added

put here value

amount of aspirin dissolved = 2.2 × 10^{-3}  × 1.4

amount of aspirin dissolved =  3.1 × 10^{-3} g

amount of aspirin dissolved = 0.0031 g

so we can say that this is not affect % yield as amount of aspirin lost is very less

Yuki888 [10]

Answer:

No

Explanation:

She will not be able to measure the length of her window accurately due to instrumental error from her choice of instrument. The elastic nature of her tape would alter the measurement because it will stretch as she is taking her readings, thus reducing the true measurement of the length of her window.

To measure the length of her window, she could use an inelastic tape rule or a metre rule. These instruments would eliminate instrumental error.

A long solenoid that has 810 turns uniformly distributed over a length of 0.380 m produces a magnetic field of magnitude 1.00 10
IRINA_888 [86]

Answer:

0.037 A

Explanation:

Magnetic field = B = 1.00 e-4 T

Length = L = 0.380 m

Number of turns = 810

B = μ₀ N I / L

⇒ Current = I = B L / μ₀ N = ( 1 e-4) ( 0.380) / (4π × 10⁻⁷)(810)

                                            = 0.037 A = 37.3 mA

Answer:

<em>The first law states that</em> every planet describes an elliptical path about the sun as a single focus.

<em>The</em><em> </em><em>second</em><em> </em><em>law</em><em> </em><em>states</em><em> </em><em>that</em><em> </em>The line joining the planet to the sun sweeps out equal areas in equal time intervals.

<em>The</em><em> </em><em>third</em><em> </em><em>law</em><em> </em><em>states</em><em> </em><em>that</em><em> </em>The squares of the period of revolution is proportional to the cubes of the mean distance between the planet and the sun
