Answer:

The correct answer will be option-Pseudoscience does not follow the scientific method, and science does.

Explanation:

A scientific investigation tries to understand the natural phenomenon and is based on the systematic approach through a scientific method whereas pseudoscience is the practice of performing scientific experiments based on personal opinions and predictions.

The pseudoscience experiments are based on the belief system which are not supported by the evidence. Therefore, the pseudoscience results are based on the co-incidences and not on the systematic approach or the scientific method.

Thus, the selected option is the correct answer.

How many grams of NaCl are needed to prepare 50.0 grams of 35.0% of salt solution?

nevsk [136]

Answer:

17.5 g

Explanation:

Given data

Mass of solution to be prepared: 50.0 grams

Concentration of the salt solution: 35.0%

The concentration by mass of NaCl in the solution is 35.0%, that is, there are 35.0 grams of sodium chloride per 100 grams of solution. We will use this ratio to find the mass of sodium chloride required to prepare 50.0 grams of a 35.0% salt solution.

$50.0gSolution \times \frac{35.0gNaCl}{100gSolution} = 17.5gNaCl$
