What is the pressure of a 3.5 mmol sample of ethane (C2H6) gas contained in a 0.500 L flask at 298 K?

-BARSIC- [3]

P = nRT/V

P = 3.5 x 10^-3 x 0.082 x 298 /0.5

P = 0.171 m Hg

P = 171 mm Hg

hope this helps

Why is co2 hard to break apart than h2o

Sergeu [11.5K]

In CO2 the dipole moments cancel out, while in H20, they don’t, making it polar. In C02, both oxygens are more electronegative than the carbon, but they pull equally apart from one another, so there is no dipole moment (the pulls cancel)

On another planet, the isotopes of titanium have the given natural abundances. Isotope Abundance Mass (amu) 46Ti 72.000% 45.9526

tiny-mole [99]

Answer:

46.784886 amu is the average atomic mass of titanium on that planet.

Explanation:

Fractional abundance of Ti-46 =72.000% = 0.72000

Atomic mass of Ti-46 = 45.95263 amu

Fractional abundance of Ti-48 =14.300% = 0.14300

Atomic mass of Ti-48 = 47.94795 amu

Fractional abundance of Ti-50 =13.700% = 0.13700

Atomic mass of Ti-50 = 49.94479 amu

$\text{Average atomic mass }=\sum_{i=1}^n\text{(Fractional abundance)}_i\times \text{(Atomic mass of an isotopes})_i$

Average atomic mass of titanium atom:

$0.72000\times 45.95263 amu+0.14300\times 47.94795 amu+0.13700\times 49.94479 amu=46.784886 amu$

46.784886 amu is the average atomic mass of titanium on that planet.
