It’s can go down to 50 degrees soo that can do
In pure water, the concentration of hydronium ions, or H⁺, will equal the concentration of hydroxide ions. That is [H⁺] = [OH⁻].
Remember that Kw = [H⁺][OH⁻] for water and if [H⁺] and [OH⁻] are both equal, we can easily solve for them by taking the square root of Kw.
[H⁺] = [OH⁻] = sqrt(1.47*10^-14) = 1.21*10^-7
The concentration of hydroxide ions at 30 degrees Celsius is 1.21*10^-7
Answer:
mass of water=29.2 g water
2 mol of water
1 mol of water=18.0 water (molar mass)
1 mol O₂=6.02 x 10²³ molescules O₂
29.2 *x* 6.02x10²³
=4.88 x 10²³
Answer:
equilateral (B)
