What is the ph of a (6.00x10^-3) m hi solution?
KatRina [158]
HI is strong acid, so:
[H+] = [HI]
[H+] = 6 × 10^-3 M

pH = -log[H+]
pH = -log(6 × 10^-3) = 2,22

The specific gravity of gold is 19.3. What is the length of one side of a 0.4 kilograms cube of solid gold, in units of inches?
zepelin [54]
Specif gravity = density of the material / density of water

density of the material = specific gravity * density of water

density of gold = 19.3 * 1 g/mL = 19.3 g/mL

density = mass / volume ==> Volume = mass / density

Volume = 0.4 kg * 1000 g/kg / 19.3 g/mL = 20.725 mL

Length of one side of the cube = \sqrt[3]{20.725 {cm}^{3} } = 2.75 cm

Pass cm to inches
2.75 cm * 1 inch / 2.54 cm = 1.08 inch
