A .332 mold sample of gas at a constant pressure and temperature has a volume of 150.0mL. If the volume of the gas is decreased

Vikentia [17]

Answer:

0.111 mol

Explanation:

We can solve this problem by using Avogadro's law, which states that at constant pressure and temperature:

V₁n₂=V₂n₁

Where in this case:

V₁ = 150.0 mL

n₂ = ?

V₂ = 50.0 mL

n₁ = 0.332 mol

We input the data given by the problem:

150.0 mL * n₂ = 50.0 mL * 0.332 mol

And solve for n₂:

n₂ = 0.111 mol

Answer:

Groups like the Halogens, which include Chlorine and Flourine, share similar properties both behaviorally and structurally. The Periodic Table is essentially a bunch of patterns and trends and the groups (like the one with Sodium and Potassium) were grouped together because of these similarities.

What is the molar concentration of 250. mL of aqueous solution containing 48.8 g of glucose, C6H12O6?

Nezavi [6.7K]

Answer:

1.08 mol/L

Explanation:

Molarity -

Molarity of a substance , is the number of moles present in a liter of solution .

$M=\frac{n}{V}$

M = molarity ( unit = mol / L or M )

V = volume of solution in liter ( unit = L ),

n = moles of solute ( unit = mol ),

Moles is denoted by given mass divided by the molecular mass ,

Hence ,

$n=\frac{w}{m}$

n = moles ,

w = given mass ,

m = molecular mass .

From the information of the question ,

V = 250 mL

Since ,

1 mL = 1/1000L

V = 0.250 L

w = 48.8 g

As we known , the mass of glucose ,

m = 180g/mol ,

From the above formula , moles is given as ,

$n=\frac{w}{m}$

substituting the corresponding values ,

n = 48.8g / 180g/mol

n = 0.27 mol

Now , the molarity can be calculated by using the above equation ,

M = n / V

substituting the corresponding values ,

M = 0.27 mol / 0.250 L

M = 1.08 mol/L
