Nick needs 3.5 moles of sodium fluoride (NaF) for a solution he is mixing in the lab. How many grams of NaF does Nick need to me
Minchanka [31]

Answer:

147 g

Explanation:

<em>The number of moles of a substance is the ratio of the mass of the substance and the molar mass of that substance.</em> Mathematically,

  mole = mass of substance/molar mass

In this case, Nick needs 3.5 moles of NaF, the molar mass of NaF is calculated as:

  23 + 19 = 42 g/mol (Note: Na = 23, F = 19)

Hence,

mass of 3.5 mole NaF = mole x molar mass

                              = 3.5 x 42 = 147 g.

<em>Hence, Nick would need to measure out </em><em>147 g</em><em> NaF using a suitable weighing balance.</em>

Which of the following statements is true? Metals usually gain electrons to fill their outermost shells. Mixtures can be broken
xxTIMURxx [149]

Explanation:

When two or more substances mix together but they do not combine chemically with each other then it is known as a mixture.

For example, sand in water is a mixture.

Mixtures can be separated by physical processes like filtration, fraction distillation etc.

Also, when a substance is soluble in another liquid then the substance is known as solute whereas the liquid is known as solvent.

A solute is always present in less quantity as compared to the solvent in a solution.

For example, gelatin powder is dissolved in hot water. Here, gelatin is the solute and hot water is the solvent.

Therefore, we can conclude that the following statements are true.

  • Mixtures can be broken apart by physical processes.
  • Gelatin powder is dissolved in hot water.
