The volume of a gas is 450 mL when its pressure is 1.00 atm. If the temperature of the gas does not change, what is the pressure
Delvig [45]

Answer:

0.225 atm

Explanation:

v1=450ml÷1000=0.45l(1l=1000ml)

P1=1

v2=2.00l

p2=?

p1v1=p2v2

p2=p1v1/v2

=1×0.45/2

=0.225

so the answer is first one

If the volume of a solution is 25.6 L and its molarity is 8.20 M, how many moles of solute are
harkovskaia [24]

Answer:

210 moles

Explanation:

From the question given above, the following data were obtained:

Volume of solution = 25.6 L

Molarity = 8.20 M

Mole of solute =?

Molarity is simply defined as the mole of solute per unit litre of water. Mathematically, it can be expressed as:

Molarity = mole /Volume

With the above formula, the mole of solute dissolved can be obtained as follow:

Volume of solution = 25.6 L

Molarity = 8.20 M

Mole of solute =?

Molarity = mole /Volume

8.20 = mole / 25.6

Cross multiply

Mole = 8.20 × 25.6

Mole = 209.92 ≈ 210 moles

Thus, the mole of solute dissolved in the solution is 210 moles
