It is required to prepare 1250 kg of a solution composed of 12 wt.% ethanol and 88 wt.% water. Two solutions are available, the
bekas [8.4K]

Answer:

437.5 kg of first solution and 812.5 kg of second solution should be mixed to get desired solution.

Explanation:

Let the mass of the first solution be x and second solution be y.

Amount solution required = 1250 kg

x + y = 1250 kg....[1]

Percentage of ethanol in required solution = 12% of 1250 kg

Percentage of ethanol in solution-1 = 5% of x

Percentage of ethanol in required solution = 25% of y

5% of x +  25% of y =12% of 1250 kg

\frac{5}{100}\times x+\frac{25}{100}y=\frac{12}{100}\times 1250 kg

x + 5y = 3000 kg...[2]

Solving [1] and [2] we :

x = 437.5 kg   , y =  812.5 kg

437.5 kg of first solution and 812.5 kg of second solution should be mixed to get desired solution.

A backpacker carries 2.7 L of white gas as fuel for her stove.How many pounds does the fuel add to her load? Assume the density
Zepler [3.9K]
2.7 L in cm³ :
 
2.7 * 1000 = 2700 cm³

Weight = Volume * Density

2700 * 0.79 = 2133 g

1 Ibs = <span>453.59 g

2133 / 453.59 = 4.70 Ibs

hope this helps!</span>

Answer:

 Answer: 760 uM

Explanation:

the addition of solvent to a solution in a such away that the volume of the solution increases and the concentration decreases is a process know as dilution

The concentration and the volume of the dilute and concentrated solution are given below as follows

     C_{1}V_{1}                               = C_{f}V_{f}

Concentrated solution          Dilute solution

Given that  M1 = 97.0uM

                  V1 = 47.0 mL

                 V2 = 6.0 mL

                 M2  = ?

Therefore M1V1   = M2V2

                M2      = M1V1/V2

                 M2 = (97*47)/6

               M2 = 760 uM

Answer: 760 uM

The melting point of copper is 1084 Celsius. How does the energy of the particles in a certain amount of liquid copper compare t
matrenka [14]
The melting point of the solid form of water, which is ice, is 0°C. When we convert both temperatures to kelvin by adding 273 to each we get the melting point of copper as 1357K and that of ice is 273K. Then, dividing the melting point of copper by the melting point of ice, both in absolute temperature scale. The answer would be 4.97. Thus, the energy of molecules of copper is approximately {five} times compared to that of water
