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.

A solution contains 3.95 g of carbon disulfide (CS2, molar mass = 76.13 g/mol) and 2.43 g of acetone ((CH3)2CO, molar mass = 58.
Feliz [49]

Answer:

The solution is not ideal and shows a positive deviation from Raoult’s law since Psolution (experimental) > Psolution (actual).

Explanation:

Number of moles of CS2 = 3.95g/76.13gmol-1 = 0.0519 moles

Number of moles of acetone = 2.43g/58.08gmol-1 = 0.0418 moles

Total number of moles = 0.0937 moles

Mole fraction of CS2 = 0.0519/0.0937 = 0.5538

Mole fraction of acetone = 0.0418/0.0937 = 0.4461

From Raoult’s law;

PCS2 = 0.5538 × 515 torr = 285.207 torr

Pacetone = 0.4461 × 332 torr = 148.1052 torr

Total pressure = 285.207 torr + 148.1052 torr = 433.3 torr

How do you find solubility? I am given only the temperature and the substance is KNO3. I don’t need anyone to solve it for me, j
skad [1K]
There’s no formula that relates solubility to temperature, but you can look up the solubility constant Ksp of substance given and then take the square root of that to find solubility.

If aqueous solutions of sodium chloride and mercury(I) nitrate are mixed, which insoluble precipitate is formed?
NeX [460]

Answer:

Hg2^2+(aq) + 2Cl^-(aq) —> Hg2Cl2(s)

Explanation:

The balanced equation for the reaction is given below:

2NaCl(aq) + Hg2(NO3)2(aq) —> 2NaNO3(aq) + Hg2Cl2(s)

Considering the states of each compound in the reaction, we can see that Hg2Cl2 is in solid form meaning it will precipitate out of the solution

In solution the following occurs:

NaCl —> Na+(aq) + Cl-(aq)

Hg2(NO3)2 —> Hg2^2+(aq) + 2NO3^-(aq)

Combining the two equation together, a balanced double displacement reaction occurs as shown below:

2Na+(aq) + 2Cl-(aq) + Hg2^2+(aq) + 2NO3^-(aq) —> 2Na+2NO3^-(aq) + Hg2^2+2Cl-(s)

From the above we can thus right the insoluble precipitate as

Hg2^2+(aq) + 2Cl^-(aq) —> Hg2Cl2(s)
