No of moles of HBr = 3.78g / 80.9 = 0.0467moles
Molarity = Number of moles/ volume. So we have 0.0467 / 4.5 = 0.0103M.
Kw = 1.0 x 10 -14 = [H3O+] [OH-] and [OH-] = 1.0 x 10^(-14) / [H3O+]
So [OH-] = 1.0 * 10^(-14) /1.03 *10^(-2) = 0.9703 * 10^(-12) M
Hey!
The property of aluminum that allows aluminum foil to change its shape is malleability.
-38.83°C
Despite being the only metal that is liquid at room temperature, mercury has the smallest liquid range of any metal. It becomes a solid at -38.83°C and a gas at 356.7°C.
