The molar volume, symbol Vm<span>, is the </span>volume occupied by one mole of a substance at a given temperature and pressure. <span>It is equal to the </span>molar<span> mass divided by the mass density. Therefore, we calculate as follows:
Vm(CO2) = 44.01 / 1.56 = 28.21 cm^3 / mol
</span>Vm(NH3) = 17.03 / 0.84 = 20.27 cm^3 / mol
The ratio of effusion rates for nitrogen and neon is calculated by use of the Grahams law formula
that is rate of N2/ rate of Ne = square root of mm of Ne/mm or N2
=square root of 20.18/28 = 0.849
Answer:
[H₃O⁺] = 0.7M
[SO₄²⁻] = 0.3M
Explanation:
The HCl in solution produce 1mole of H₃O⁺ and H₂SO₄ produce 2 moles of H₃O⁺.
When two solutions are mixing in equal volumes, the concentrations of both reactants is halved regard to their initial concentrations. That is:
HCl = 0.1M
H₂SO₄ = 0.3M
And H₃O⁺ will be:
0.1M + 2*0.3M = 0.7M
And SO₄²⁻ comes just from H₂SO₄, that means:
[H₂SO₄] = [SO₄²⁻] = 0.3M
