<h2>Hello!</h2>

The answer is:

The percent yield of the reaction is 32.45%

<h2>Why?</h2>

To calculate the percent yield, we have to consider the theoretical yield and the actual yield. The theoretical yield as its name says is the yield expected, however, many times the difference between the theoretical yield and the actual yield is notorious.

We are given that:

ActualYield=37.6g\\TheoreticalYield=112.8g

Now, to calculate the percent yield, we need to divide the actual yield by the theoretical and multiply it by 100.

So, calculating we have:

PercentYield=\frac{ActualYield}{TheoreticalYield}*100\\\\PercentYield=\frac{37.6g}{112.8g}*100=0.3245*100=32.45(percent)

Hence, we have that the percent yield of the reaction is 32.45%.

Have a nice day!

We need to find what percent 37.6 is out of 112.8 .

First find what fraction of 112.8 it is:  (37.6/112.8) = 1/3

Change the number to a percentage:  (1/3 x 100) = <em>(33 and 1/3) %</em>

To what temperature should 2.3L of a gas at 25degree Celsius be heated in order to expand its volume to 4 L under constant press
lakkis [162]

Answer:

518.52K

Explanation:

Charles law, which describes the direct relationship between the volume and the temperature of a gas when the pressure is constant, will be used for this question. The Charles law equation is:

V1/T1 = V2/T2

Where; V1 is the volume of the gas at an initial state (Litres)

T1 is the absolute temperature of the gas at an initial state (Kelvin)

V2 is the volume of the gas at a final state (Litres)

T2 is the absolute temperature of the gas at a final state (Kelvin)

According to the question, V1 = 2.3L, T1 = 25°C, V2 = 4L, T2 = ?

We need to convert the temperature to the absolute temperature unit in Kelvin (K) i.e.

T(K) = T(°C) + 273.15

T(K) = 25°C + 273.15

T1 (K) = 298.15K

To find for T2 in the equation, we make T2 the subject of the formula:

T2 = V2 × T1 / V1

T2 = 4 × 298.15 / 2.3

T2 = 1192.6/2.3

T2 = 518.52

Thus, the temperature must be heated to 518.52K in order to expand to a volume of 4L. This answer is in accordance to Charles law that the volume increases with increase in temperature and vice versa.

3. You are preparing 285 mL of 70% (v/v) ethanol in water using a 95% ethanol stock. Round your answer to the nearest whole numb
attashe74 [19]

Answer:

a) 210 mL of 95% ethanol

b) 75 mL of water

Explanation:

a) We can use the dilution equation to solve this problem. C₁ and V₁ are the concentration and volume of the stock solution, respectively, while C₂ and V₂ are the concentration and volume of the diluted solution.

C₁V₁ = C₂V₂

We want to find V₁, the volume of ethanol stock we need to dilute to prepare the final solution:

V₁ = (C₂V₂) / C₁

The concentrations are represented in percentages. We substitute in the known values to calculate V₁. The units cancel to leave us with units of mL.

V₁ = (C₂V₂) / C₁ = (70%)(285mL) / (95%) = 210 mL

b) The final solution volume is 285 mL and we have added 210 mL of ethanol, so the remaining volume is from the water that we add:

(285 mL - 210 mL) = 75 mL

Calculate the missing variables in each experiment below using Avogadro’s law.
blagie [28]

Answer:

The answer to your question is: letter c

Explanation:

Data

V1 = 612 ml    n1 = 9.11 mol

V2 = 123 ml    n2 = ?

Formula

                               \frac{V1}{n1}  =  \frac{V2}{n2}

                                         n2 = \frac{n1V2}{V1}

                                         n2 = \frac{(9.11)((123)}{(612)}

                                                n2 = 1.83 mol
