<u>Answer:</u> The density of alcohol is 0.705 g/mL

<u>Explanation:</u>

To calculate density of a substance, we use the equation:

\text{Density of substance}=\frac{\text{Mass of substance}}{\text{Volume of substance}}

We are given:

Mass of alcohol = 7.05 g

Volume of alcohol = 10 mL

Putting values in above equation, we get:

\text{Density of alcohol}=\frac{7.05g}{10mL}=0.705g/mL

Hence, the density of alcohol is 12.38 g/mL

Density is mass per unit volume. The units you specified are grams per ml.

So simply divide 7.05g by 10 ml.

=0.705g/ml.

How many mL of 8.00M HCl solution are needed to make a dilution with a final volume of 2,500.ml, and a
kompoz [17]

Answer:

104.1 mL

Explanation:

c1V1 = c2V2

V1 = c2V2/c1 = (0.333 M×2500 mL)/8.00 M

V1 = 104.1 mL

37.2 liters of a gas has a pressure of 362.43 kPa at 46.5 °C. If the pressure increases to
Nataliya [291]

Answer:

Option A. 25.7 L.

Explanation:

Step 1:

Data obtained from the question. This include the following:

Initial volume (V1) = 37.2 L

Initial pressure (P1) = 362.43 kPa

Initial temperature (T1) = 46.5 °C

Final pressure (P2) = 693.9 kPa

Final temperature (T2) = 149.2 °C

Final volume (V2) =.?

Step 2:

Conversion of celsius temperature to Kelvin temperature.

This can be achieved as shown below:

Temperature (K) = Temperature (°C) + 273

T (K) = T (°C) + 273

Initial temperature (T1) = 46.5 °C

Initial temperature (T1) = 46.5 °C + 273 = 319.5 K.

Final temperature (T2) = 149.2 °C

Final temperature (T2) = 149.2 °C + 273 = 422.2 K.

Step 3:

Determination of the new volume.

This can be obtained by using the general gas equation as shown below:

Initial volume (V1) = 37.2 L

Initial pressure (P1) = 362.43 kPa

Initial temperature (T1) = 319.5 K

Final pressure (P2) = 693.9 kPa

Final temperature (T2) = 422.2 K

Final volume (V2) =.?

P1V1/T1 = P2V2/T2

362.43×37.2/319.5 = 693.9 × V2/422.2

Cross multiply

319.5×693.9×V2 = 362.43×37.2×422.2

Divide both side by 319.5 × 693.9

V2 = (362.43×37.2×422.2)/(319.5×693.9)

V2 = 25.7 L

Therefore, the new volume is 25.7 L.

Given the equation:
Citrus2011 [14]

Answer: a)  Fe is the limiting reagent

b) 3.59 g

c) 11.6g

Explanation:

4Al_2O_3+9Fe\rightarrow 3Fe_3O_4+8Al  

To calculate the moles :

   

\text{Moles of} Al_2O_3=\frac{27.5g}{102g/mol}=0.27moles

\text{Moles of} Fe=\frac{8.4g}{56g/mol}=0.15moles

According to stoichiometry :

a) 9 moles of Fe  require= 4 moles of Al_2O_3

Thus 0.15 moles of Fe will require=\frac{4}{9}\times 0.15=0.067moles  of Al

Thus Fe is the limiting reagent as it limits the formation of product and Al is the excess reagent.

b) As 9 moles of Fe give = 8 moles of Al

Thus 0.15 moles of Fe give =\frac{8}{9}\times 0.15=0.133moles  of Al

Mass of Al=moles\times {\text {Molar mass}}=0.133moles\times 27g/mol=3.59g

c) As 9 moles of Fe give = 3 moles of Fe_3O_4

Thus 0.15 moles of Fe give =\frac{3}{9}\times 0.15=0.05moles  of Fe_3O_4

Mass of Fe_3O_4=moles\times {\text {Molar mass}}=0..05moles\times 231.5g/mol=11.6g
