What is the hydronium and hydroxide concentrations of a solution that is 5.0 x 10-3 M H2SO4.
Maksim231197 [3]

The hydronium and hydroxide concentrations of a solution that is 5.0 x 10-3 M H2SO4 is 2.7.

pH= -log[H+] - (i)

10^-3=H2So4

H+= 2×10-3

here ,

h2so4 ——— 2[H+] + so4^2-

thus [H+]= 2*10^(-3) because hydrogen ion has two moles

pH= -log[H+]

pH= -log(2×10^-3)

pH= 3-log2

pH= 3-log2pH= 2.7

The pH is 2.7

<h3>What is pH?</h3>

PH is the degree of alkalinity and acidicity in a solution.

Therefore, The hydronium and hydroxide concentrations of a solution that is 5.0 x 10-3 M H2SO4 is 2.7

torisob [31]

Answer:

a) 9424797000 m3

b) 9424797000000 liters

c) 9424797000000 kg

Explanation

Cylinder has a radius of 1 km= 1000 m.

Area Cylinder = π r^2  =  3,141599* (1000m)^2  = 3141599 m2

a) Volume Cylinder= area x Height=3141599 m2* 3000 m=  9424797000 m3

b) 1000 liters= 1m3,   9424797000 * 1000 = 9424797000000 liters

c) densiy = 1000 kg/m3, or 1 kg/ liter,   mass=  9424797000 lt * 1kg/lt =

9424797000 kg
