1.64 + 4.66 = 6.3
1.64/6.3 = 0.2603174603 = 26%

Answer : The percentage of salt in the mixture is 73.65 %

Explanation : Given,

Mass of salt = 1.64 lb

Mass of water = 4.66 lb

First we have to calculate the mass of mixture.

Mass of mixture = Mass of salt + Mass of water

Mass of mixture = 1.64 + 4.66 = 6.3 lb

Now we have to calculate the percentage of salt in the mixture.

Formula used :

\% \text{ of salt}=\frac{\text{Mass of salt}}{\text{Mass of mixture}}\times 100

Now put all the given vales in this formula, we get:

\% \text{ of salt}=\frac{4.64lb}{6.3lb}\times 100=73.65\%

Therefore, the percentage of salt in the mixture is 73.65 %

Calculate the freezing point of a solution 1.25 g benzene (C6H6) in 125 g of chloroform (CHCl3).
posledela

Answer:

The freezing point for the solution is -64.09°C

Explanation:

This problem can be solved, by the freezing point depression. This colligative problem shows, that the freezing point of a solution is lower than the freezing point of pure solvent.

ΔT = Kf.  m

ΔT = T° freezing pure solvent - T° freezing solution

Kf = Cryscopic constant, for chloroform is 4.68

T°freezing pure solvent = -63.5°C

m is mol/kg of solvent → molality

Let's determine the moles of benzene

1.25 g / 78 g/mol = 0.0160 mol

Let's convert the mass of solvent to kg

125 g . 1kg / 1000 g = 0.125 kg

m = 0.0160 mol / 0.125 kg → 0.128 m

Let's go to the formula to replace the data

-63.5°C - T° freezing solution = 4.68 °C/m . 0.128 m

T° freezing solution = - (4.68 °C/m . 0.128 m + 63.5°C)

T° freezing solution = - 64.09°C

What type of plate boundary would form where there is a mountain range present, known earthquake activity, but no trenches prese
Natasha_Volkova [10]

Answer:

continental-continental convergent boundary

Explanation:

When two continental plates converge, they smash together and create mountains. The amazing Himalaya Mountains are the result of this type of convergent plate boundary. The Appalachian Mountains resulted from ancient convergence when Pangaea came together.

TRUE FALSE? The MOLE is a unit in Chemistry that serves as a bridge between the ATOMIC and MACROSCOPIC worlds?​
Vanyuwa [196]

Answer:

True

Explanation:

A mole is defined as 6.02214076 × 1023 of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.
