Hello:
In this case, we will use the Clapeyron equation:
P = ?
n = 8 moles
T = 250 K
R = 0.082 atm.L/mol.K
V = 6 L
Therefore:
P * V = n * R * T
P * 6 = 8 * 0.082* 250
P* 6 = 164
P = 164 / 6
P = 27.33 atm
Hope that helps!
The magma is heated and becomes less dense by the core moving it toward the crust.
Explanation:
Magma is a molten or partially molten rock form. Magma consists of silicate liquid, although carbonate and sulfide melts occur as well. It moves either to depth or to Earth’s surface and is ejected as lava. Suspended crystals and fragments of un-melted rock get transported in the magma dissolved volatiles may separate as bubbles and some liquid get crystallize during movement.
Several interrelated physical properties determine the characteristics of magma, including chemical composition, viscosity, dissolved gases, and temperature.Magma also form igneous rock.
Therefore the magma is heated and becomes less dense by the core moving it toward the crust.
Since all of those percents add up to 100, you can just directly convert that to grams. So now you can use 2 grams H, 32.7 grams S, and 65.3 grams O. Use that info and convert that to moles for an answer of 2mol H, 1mol S, and 4mol O. In every empirical question you need to divide each quantity of moles by the lowest number. In this case, that number is one, so they stay the same, but it's important to remember that step. You're final chemical formula would be H2SO4 and the answer to your question would be that the subscript for oxygen is 4. Hope this helped!
