CALCULATE: Determine the volume occupied by 0.582 mol of a gas at 15 degrees Celsius if the pressure is 81.8 KPA?

7nadin3 [17]

PV=nRT

So

NRT/P=V ...
SI units for pressure is pascals so 81.8KPA = 81.8 x 10^3 PA
SI units for temperature is kelvin so 15 degrees celsius = 15 +273 = 288K

(0.582 x 8.314 x 288)/81.8 x 10^3 = 0.017 m3 (cubic meters)

Which of the following sets of empirícal formula, molar mass, and molecular formula is correct?

skad [1K]

Answer:

The option C is correct.
CH4N, 90g, C3H12N3.

Explanation:

Option C:

The molecular formula is C3H12N3.

If we take ratio 3:12:3 that will be equal to 1:4:1 so its empirical formula will be CH4N.
The molar mass of molecular formula = (12×3) + (1×12) +( 14×3) = 98 g

Option A :

In option A , molecular and empirical formula are both correct but molar mass is not valid. It should be 169 acc. to molecular formula.

Option B:

In option B, molecular formual is not valid.
It should be as C6H16O2
