A 2% saltwater is a dilute solution in which the solvent is water and the solute is salt. The solvent is the component of the solution which comprise a large percentage while the solute comprise the smaller part. When alcohol is added, the solute still is salt and the solvent is the mixture of water and alcohol.
Answer:
<h3>The answer is 41.05 %</h3>
Explanation:
The percentage error of a certain measurement can be found by using the formula

From the question
actual density = 0.95 g/mL
error = 0.95 - 0.56 = 0.39
So we have

We have the final answer as
<h3>41.05 %</h3>
Hope this helps you
A circle graph, or a pie chart or graph, would be the type of graph that is best used when showing the <span>percentage of reactant molecules that collide during a reaction in a graphical representation. In addition, the circle graph mainly consists of a circle being divided into parts proportional to the whole.</span>
120 grams of NaOH means 3 Moles of NaOH because 40 grams (Molecular Weight in grams) is one mole of NaOH.
Each mole of any substance contain Avogadro’s number of molecules ie., 6.022 x (10 to the power 23).
Hence 3 Moles of NaOH contain 3 times of Avogadro’s number of molecules ie., 3 x 6.022 x (10 to the power 23)
