You perform a distillation to separate a mixture of propylbenzene and cyclohexane, and you obtain 2.9949 grams of cyclohexane (d

Romashka-Z-Leto [24]

Answer:

66.67%

Explanation:

From the given information:

mass of cyclohexane = 2.9949 grams

density of cyclohexane = 0.779 g/mL

Recall that:

Density = mass/volume

∴

Volume = mass/density

So, the volume of cyclohexane = 2.9949 g/ 0.779 g/mL

= 3.8445 mL

Also,

mass of propylbenzene = 1.6575 grams

density of propylbenzene = 0.862 g/mL

Volume of propylbenzene = 1.6575 g/ 0.862 g/mL

= 1.9229 mL

The volume % composition of cyclohexane from the mixture is:

$= (\dfrac{v_{cyclohexane}}{v_{cyclohexane}+v_{propylbenzene}})\times 100$

$= (\dfrac{3.8445}{3.8445+1.9229})\times 100$

$= (\dfrac{3.8445}{5.7674})\times 100$

= 66.67%

atroni [7]

Answer:

Ammonium chloride

Explanation:

The powder is:- Ammonium chloride

When mixed with silver nitrate, white prescipitate of silver chloride is formed as:-

$NH_4Cl+AgNO_3\rightarrow NH_4NO_3+AgCl$

When mixed with sodium hydroxide, ammonia gas is formed which has noxious order.

$NH_4Cl +NaOH\rightarrow NH_3 + H_2O + NaCl$

Ammonia gas on reaction with nickel (II) hydroxide forms deep blue colored complex as shown below:-

$Ni(OH)_2(s) + 6NH_3(aq)\rightarrow [Ni(NH_3)_6]^{2+}(aq) + 2OH^{-}(aq)$

The density of ethanol is 0.789 g/mL. If you need 460.0 g of ethanol for an experiment, how many milliliters would you measure o

4vir4ik [10]

Answer:

The volume is 583.02 mL

Explanation:

Given that the density is:-

$\rho=0.789\ g/mL$

The mass, $m=460.0\ g$

The expression for the calculation of density is shown below as:-

$\rho=\frac{m}{V}$

Using the above expression to calculate the volume as:-

$V=\frac{m}{\rho}$

Applying the values to calculate the volume as:-

$V=\frac{460.0\ g}{0.789\ g/mL}=583.02\ mL$

<u>The volume is 583.02 mL.</u>
