Answer:

The answer to your question is T = 7.25 °K

Explanation:

Data

Temperature = ?

moles = 0.80

volume = 275 ml

pressure = 175 kPa

constant of ideal gases = 0.082 atm l/ mol °K

Process

1.- Use the ideal gas law to solve this problem

PV = nRT

-Solve for Temperature

T = PV / nR

2.- Convert Pressure to atm

1 atm --------------- 101.325 kPa

x --------------- 175 kPa

x = (175 x 1) / 101.325

x = 1.73 atm

3.- Convert volume to liters

1000 ml ---------------- 1 l

275 ml ----------------- x

x = (275 x 1) / 1000

x = 0.275 l

4.- Find the temperature

T = (0.275 x 1.73) / (0.8 x 0.082)

-Simplification

T = 0.476 / 0.0656

-Result

T = 7.25 °K

Which element is a liquid at STP?<br> (1) bromine (3) francium<br> (2) cesium (4) iodine

ollegr [7]

Among the choices, bromine exists as liquid under standard temperature and pressure conditions. Unlike other diatomic molecules which exist as gases, due to its heavy molecular weight, it exists as solid. Francium and cesium are solids while iodine is gas.Answer is 1.

Fofino [41]

Answer:

(a) $102.6g/mol$

(b) Rubidium

Explanation:

Hello,

This titration is carried out by assuming that the volume of base doesn't have a significant change when the mass is added, thus, we state the following data a apply the down below formula to compute the molarity of the base solution:

$V_{base}=0.1L; M_{acid}=2.5M, V_{acid}=0.017L\\V_{base}M_{base}=V_{acid}M_{acid}$

Solving for the molarity of base we've got:

$M_{base}=\frac{M_{acid}*V_{acid}}{V_{base}}=\frac{2.50M*0.017L}{0.1L} =0.425M=0.425mol/L$

Now, we can compute the moles of the base as:

$n_{base}=0.425mol/L*0.1L=0.0425mol$

(a) Now, one divides the provided mass over the previously computed moles to get the molecular mass of the unknown base:

$\frac{4.36g}{0.0425mol} =102.6g/mol$

(b) Subtracting the atomic mass of oxygen and hydrogen, the metal's atomic mass turns out into:

$102.6g/mol-16g/mol-1g/mol=85.6g/mol$

So, that atomic mass dovetails to the Rubidium's atomic mass.

Best regards.

What is concentration

Arlecino [84]

Answer:

Chemistry definition: Concentration Definition. In chemistry, concentration refers to the amount of a substance per defined space. Another definition is that concentration is the ratio of solute in a solution to either solvent or total solution. Concentration usually is expressed in terms of mass per unit volume.

Dictionary Definition: the action or power of focusing one's attention or mental effort
