kompoz [17]3 years ago
5 0

Answer:

0.01235 moles

Explanation:

<em>Given data:</em>

volume = 47.5 ml = 0.0475 L

concentration = 0.260 M

<em>To  find:</em>

number of  moles: ?

<em>Formula:</em>

No of moles = concentration x volume (in litres)

M is equal to moles per liter, so if you multiply the volume in liters times the value of M, the result will tell you the number of moles.  

<em>Solution: </em>

no. of moles = 0.260 M x 0.0475 L

= 0.01235 moles

What is the final volume (L) of a 1.00 L system at 315 K and 1.10 atm if STP conditions are established?
LenaWriter [7]

Answer:

0.95L

Explanation:

Data obtained from the question include:

V1 (initial volume) = 1L

T1 (initial temperature) = 315K

P1 (initial pressure) = 1.10 atm

T2 (final temperature) = stp = 273K

P2 (final pressure) = stp = 1atm

V2 (final volume) =?

Using the general gas equation P1V1/T1 = P2V2/T2, the final volume of the system can be obtained as follow:

P1V1/T1 = P2V2/T2

1.1 x 1/315 = 1 x V2/273

Cross multiply to express in linear form.

315 x V2 = 1.1 x 273

Divide both side by 315

V2 = (1.1 x 273) /315

V2 = 0.95L

Therefore, the final volume of the system if STP conditions are established is 0.95L
