You have at your disposal 3 1-pound bags of various pure salts that dissolve readily in water. You can add one of the bags to a

Sedaia [141]

Answer:

This question appears incomplete

Explanation:

However, it should be noted that addition of soluble salts generally lowers the freezing point of water hence after the addition, water will no longer freeze at 0°C but lower.

Soluble salts tend to form more ions in water, it is these ions that are responsible for interfering with the hydrogen bonds hence lowering the freezing. Thus, (since each bag are of the same weight) <u>the bag that contains the salt that ionizes more in water will lower the freezing point by the greatest amount</u>.

NOTE: Different weight of the salts could lead to more ions been formed in the water by some salts as against the other.

What volume of a substance will have a mass exactly 750 g if the specific gravity of the substance is 12.2

Ket [755]

The volume of the substance is 61.4 litres.

Explanation:

Specific density is the ratio of density of a substance at a given temperature with the density of reference substance.

Data given:

mass = 750 grams

specific gravity = 12.2

volume=?

The formula to be used:

Specific gravity = $\frac{density of the object}{density of the reference substance}$

suppose the other substance is water so its density is 1g/ml at 4 degrees

Putting the values to the equation:

density of the object = 1 x12.2

density of the substance = 12.2

Now using the formula:

density = $\frac{mass}{volume}$

putting the values in the equation:

volume = $\frac{750}{12.2}$

= 61.4ml is the volume of the substance.

An unknown rectangular substance measures 3.60cm high, 4.21cm long, and 1.17cm wide. If the mass is 21.3g what is this substance

tino4ka555 [31]

The rectangular substance measures 3.60cm high, 4.21cm long, and 1.17cm wide. If the mass is 21.3g substances density will be 1.20 centimeter cube.

<h3>What is density?</h3>

The density of any substance is the ratio of the mass of substance to the volume of the substance and the unit will be centimeter cube.

The volume of the substance will be 3.60cm high × 4.21cm long ×1.17cm wide = 17.7 milliliters.

density = mass of substance / volume of substance

Substituting the value in formula

Density = 21.3g / 17.7 milliliters.

Density = 1.20 centimeter cube.

Therefore, rectangular substance measures 3.60cm high, 4.21cm long, and 1.17cm wide. If the mass is 21.3g substances density will be 1.20 centimeter cube.
