In the combined gas law, if the volume is decreased, what happens to the temperature if pressure remains constant?
Flura [38]

The correct answer is A. In the combined gas law, if the volume is decreased and the pressure is constant, then the temperature decreases.

 <span>P1V1/ T1 = P2V2 / T2</span>

 <span>Assume the volume decrease by half; V2 = V1/2</span>

 <span>P1V1/ T1 = P2V1 /2 T2</span>

 <span>Cancelling terms,</span>

 <span>1/T1 = 1/2 T2</span>

T2 = T1/2

 <span>Thus, the temperature decreased.</span>

how many moles of solute are contained in 500.00 milliliter solution that has a concentration of 0.35M
igomit [66]

1.75 moles of Solute or 1.75n.

To find this, you'll need to use the molarity equation which is M = \frac{n}{v}

List the given items to organize better:

M (Molarity) = .35

V (Volume) = 5L [must always be in Liters]

n (Moles) = ?

Now, for the equation, substitute the variables with the given numbers:

.35 = \frac{n}{5}

Isolate the variable by multiplying the volume, 5, onto both sides. This will give you the answer of:

1.75 = n

Hope this helps!
