Answer:

Explanation: a simple solution is basically two substances that are evenly mixed together. one of them is called the solute and the other is the solvent. solute is the substance to be dissolved (sugar).

am not sure if that is the answer but hopefully it helps.

Answer:

Solute is a substance which is dissolved in solvent to make solution

Explanation:

Now, point here to understand is, how can we differentiate solute from a solvent. Important thing to remember is, solute is in lesser quantity in liquid solutions.

Now solute is dissolves in solvent to make solution. In our daily life, there are many examples of solute. Like, sugar in tea is solute and liquid tea is solvent, salt in water is a solute and water acts as solvent.

Now notice that there is a particular quantity of substance in a solvent acts as a solute. Molarity is one of the ways to express concentration of solute and represent as M which is moles. Now molarity is used to determine both quantity of solvent or concentration of solute.

Molarity = Number of moles of solute/Liters of solution

Find the volume of a gas at standard pressure if its volume at 1.9 atm is 80 ml?

kogti [31]

Answer:

1.5 × 10² mL

Explanation:

Step 1: Given data

Initial pressure of the gas (P₁): 1.9 atm

Initial volume of the gas (V₁): 80 mL

Final pressure of the gas (P₂): 1.0 atm (standard pressure)

Final volume of the gas (V₂): ?

Step 2: Calculate the final volume of the gas

For an ideal gas, we can calculate the final volume of the gas using Boyle's law.

P₁ × V₁ = P₂ × V₂

V₂ = P₁ × V₁/P₂

V₂ = 1.9 atm × 80 mL/1.0 atm

V₂ = 1.5 × 10² mL

Since the pressure decreased, the volume of the gas increased.

An environmental scientist developed a new analytical method for the determination of cadmium (cd^2+) in mussels. To validate th

Anettt [7]

Answer:

The method is accurate in the calculation of the $Cu^+2$

Explanation:

As a first step we have to calculate the <u>average concentration </u>of $Cu^+2$ find it by the method.

$\frac{0.782+0.762+0.825+0.838+0.761 }{5} =0.79 ppm$

Then we have to find the<u> standard deviation:</u>

$s=\sqrt{\frac{1}{N-1}\sum_{i=1}^N(x_i-\bar{x})^2}=0.0359$

For the confidence interval we have to use the formula:

μ=Average± $\frac{t*s}{\sqrt{n} }$

Where:

t=t student constant with 95 % of confidence and 5 data=2.78

μ= $0.79$ ± $\frac{2.78*0.0359}{\sqrt{5} }$

upper limit: 0.84

lower limit: 0.75

If we compare the limits of the value obtanied by the method (Figure 1 Red line) with the reference material (Figure 1 blue line) we can see that the values obtained by the method are within the values suggested by the reference material. So, it's method is accurate.
