25.0 grams of argon are placed in a 20.00l container and the pressure is determine to be 1.250 atm. what is temperature of the gas?

487.02 K.

Explanation:

where, P is the pressure of the gas in atm.

V is the volume of the gas in L.

n is the no. of moles of the gas in mol.

R is the general gas constant (R = 0.082 L.atm/mol.K),

T is the temperature of the gas in K.

P = 1.25 atm, V = 20.0 L, R = 0.082 L.atm/mol.K, n = mass/molar mass = (25.0 g)/(39.948 g/mol) = 0.626 mol.

∴ T = PV/nR = (1.25 atm)(20.0 L)/(0.626 mol)(0.082 L.atm/mol.K) = 487.02 K.

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
