poizon [28]

D. Sometimes it is necessary to put forth new theories to explain  experimental results,

Explanation:

Creativity is important to science because sometimes, it is necessary to put forth new theories to explain experimental results.

Theories are explanation of scientific observations.

  • Most scientists are critical and creative thinkers.
  • They must be able to come up with a wide range of possible explanation to explain their findings.
  • The explanations must be scientific in nature and not fall out of the basic tenets of this way of thinking.
  • Therefore, scientists draw from their wealth of deductive reasoning to give explanations into an observed phenomenon.

Calculate the mass percent (m/m) of a solution prepared by dissolving 51.56 g of NaCl in 164.2 g of H2O. Express your answer to
denis-greek [22]

Answer:

"23.896%" is the right answer.

Explanation:

The given values are:

Mass of NaCl,

= 51.56 g

Mass of H₂O,

= 165.6 g

As we know,

⇒  Mass of solution = Mass \ of \ (NaCl+H_2O)

                                 = 51.56+164.2

                                 = 215.76 \ g

hence,

⇒ Mass \ percent =\frac{Mass \ of \ NaCl}{Mass \ of \ solution}\times 100

                           =\frac{51.56}{215.76}\times 100

                           =23.896 \ percent
