Answer:

1.73 M

Explanation:

Molarity is moles per liter, so we need to divide 7.47 moles by 4.31 liters to get the molarity of the solution.

7.47/4.31 ≈ 1.73 M

Phoenix [80]

Answer:

The volume of the gas at given temperature is $1300 cm^3$

Explanation:

$P_1$ = initial pressure of gas = 1 atm

$T_1$ = initial temperature of gas = $0^oC=273.15 K$

$V_1$ = initial volume of gas = $310 cm^3 = 310 mL = 0.310 L$

( $1 cm^3= 1mL$ , 1 mL = 0.001 L)

$P_1V_1=nRT_1$ ..[1]

$P_2$ = final pressure of gas = 2.1 atm

$T_2$ = final temperature of gas = $2,200^oC=273+2200 K=2473.15 K$

$V_2$ = final volume of gas = ?

$P_2V_2=nRT_2$ ..[2]

By dividing [1] and [2] we get combined gas equation :,

$\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}$

$V_2=\frac{P_1V_1\times T_2}{T_1\times P_2}$

Now put all the given values in the above equation, we get:

$V_2=\frac{1 atm\times 0.310 L\times 2473.15 K}{273.15 K\times 2.1 atm}$

$V_2=1.3 L=1300 mL= 1300 cm^3$

The volume of the gas at given temperature is $1300 cm^3$

A geochemist in the field takes a 25.0 mL sample of water from a rock pool lined with crystals of a certain mineral compound X .

san4es73 [151]

Answer:

1- Yes, we can calculate the solubility of mineral compound X.

2- 0.012 g/mL.

Explanation:

1- Using only the information above, can you calculate the solubility of X in water at 15.0 °C?

The information available is:

The volume of water sample = 25.0 mL.

Weight of the mineral compound X after evaporation, drying, and washing = 0.30 g.

∴ Yes, we can calculate the solubility of mineral compound X.

2- If you said yes, calculate it.

∵ 25.0 mL of water sample contains → 0.30 g of the mineral compound X.

∴ 1.0 mL of water sample contains → ??? g of the mineral compound X.

1.0 ml of water sample will contain (0.3 g/25.0 mL) 0.012 g.

∴ The solubility of the mineral compound X in the water sample is 0.012 g/mL.

1. As Z stays constant and the number of electrons increases, the electron-electron repulsions _____, and the anion becomes larg

Ray Of Light [21]

Answer:

1) increases

2) smaller

Explanation:

Generally, as electron- electron repulsion increases and more electrons are added to the atom while Z is held constant, the electron cloud size is increased. The size of the anion formed is usually measured as the size of this extended electron cloud. Hence the larger electron cloud means a larger anion size compared to the size of the neutral atom.

For a cation, the converse is true and the cation is found to be smaller than the neutral atom.
