Calculate the percent by mass when 40.0 grams of NaCl is dissolved into enough water to make 100. grams of solution.

Chemistry
1 answer:

3 0

Answer:

Percent by mass when 40.0 grams of NaCl is dissolved into enough water to make 100. grams of solution is 40% .

Explanation:

Given,

Mass of NaCl = 40 grams

Mass of Solution = 100 grams

In this solution, NaCl is solute and Water is the solvent.

Mass percent of a solution can be calculated using the formula,

Mass percent =  (Mass of Solute/Mass of Solution)x(100)

As NaCl is solute, mass of solute = 40 grams

 Mass of solution = 100 grams

Substituting the values, Mass percent = (40/100)x(100) = 40%

Why are salt and sugar both able to dissolve in water, even though the solutes have different types of chemical bonding? everyth
Bas_tet [7]

Sucrose and other simple sugars may dissolve in water because they are polar molecules with an unequal charge distribution. Water is also quite polar, capable of forming weak, temporary connections with other polar compounds.

Salt dissolves into ions, with Na being positively charged and CL being negatively charged. Because water is highly polar (parts of the molecule are negatively charged while others are positively charged), the sodium ions are surrounded by water molecules, with the negatively charged component of the water molecules surrounding the NA ion. The Cl ion experiences the inverse effect.

<h3>How does salt dissolve in water compared to sugar?</h3>

A solution's solute and solvent are two different types of substances that can dissolve one another. Different solvents have different levels of solubility for different solutes. For instance, sugar is far more soluble in water than salt. Even sugar, though, has a limit on how much may dissolve.

Dichlorine monoxide, Cl2O is sometimes used as a powerful chlorinating agent in research. It can be produced by passing chlorine
Amiraneli [1.4K]

Answer:

% yield =  82.5%

Explanation:

HgO + 2Cl₂ →  HgCl₂ +  Cl₂O

Our reactants are:

  • HgO and Cl₂

Our products are:

  • HgCl₂ +  Cl₂O

We do not have information about moles of reactants, but we do know the theoretical yield and the grams of product, in this case Cl₂O, we have produced.

Percent yield = (Yield produced / Theoretical yield) . 100

Theoretical yield is the mass of product which is produced by sufficent reactant. We replace data:

% yield = (0.71 g/0.86g) . 100 = 82.5%
