So really you only need to answer the first one because you have more than enough og everything. 2×(what)=14 then that will be your answer
Answer:
I think its D
Explanation:
It cant be B or C bc the solute particles arent changing. And its not A because the concentration isnt constant
Answer:
[H₃O⁺] = 6.31 x 10⁻³ M.
Explanation:
- To find the hydronium ion concentration [H₃O⁺], we can use the relation:
<em>pH = - log[H₃O⁺].</em>
<em></em>
∴ 2.2 = - log[H₃O⁺].
∴ log[H₃O⁺] = - 2.2
<em>∴ [H₃O⁺] = 6.31 x 10⁻³ M.</em>
Explanation:
rate of diffusion of H2S is about one Fourth times faster than that of SO2 by what factors is the rate of diffusion of ammonia faster than that
Answer:
moles Hg = 25.8 / 200.59 = 0.129
atoms = 0.129 x 6.02 x 10^23 =7.74 x 10^22
Moles Zn = 0.0340 / 65.39 =0.000520
atoms = 3.13 x 10^20
work in the same way : divide the mass by the molar mass and multiply by 6.02 x 10^23
