Hey there!:
Volume of rainfall = Area X height
Height = 1 in = 0.254 dm
1mile2 = 2.59 X 10⁸ dm²
so 1300 miles² = 3367 *10⁸ dm²
Volume = 0.254 * 3367 * 10⁸ = 855.218 * 10⁸ dm³
Also,
H2SO4 ionizes as :
H2SO4 --> H⁺ + HSO4⁻
Ka1 is very high so it completely dissociates , due to first dissociation [H⁺] = Concentration of H2SO4
HSO4⁻ --> H⁺ + SO₄⁻²
We also consider it as high dissociation :
so each mole of H2SO4 will give 2 moles of H⁺ (proton)
pH = 3.30 = -log[H⁺]
So [H+] = 0.000501 M = 0.000501 moles / L or moles / dm³
Volume = 855.218 * 10⁸dm³
so moles of H+ present in this volume:
= 0.000501 * 855.218 *10⁸ = 4.28* 10⁷moles
So moles of H2SO4 = 4.28 * 10⁷ / 2 = 2.14 * 10⁷ moles
Molecular weight of H2SO4 = 98 g / mol
Mass of H2SO4:
Moles X molecular weight = 98 * 2.14 X 10⁷ grams = 209.72 * 10⁷ grams in kg:
= 2.09 X 10⁶Kg
Hope that helps!
Answer:
3.6mol Li
Explanation:
To get the amount of moles from the mass we divide the mass by the molar mass.
25g ÷ 6.941g/mol = 3.6mol Li
The calculated molar volume would decrease as CO2 would escape
Potassium is a chemical element
Symbol: K
Atomic number: 19
Atomic mass: 39.0983 u ± 0.0001 u
Electron configuration: [Ar] 4s1
Melting point: 146.3°F (63.5°C)
For the answer to the question above,
322Joules of heat energy is added to the system (gold bar) while no work is done on the gold bar, this is an isochoric/isovolumetric process, thus
<span>ΔU = 322J + 0 </span>
<span>=322J </span>
<span>Therefore the internal energy increase by <u>322J
