In order to discuss pH the acid has to be dissolved in a measured volume of solvent (in this case probably water). A mole is a measure of amount. So all you have given us is an amount of acid. We also have to know the amount of water you are going to use to make the solution.

Calculate the mass of carbon dioxide present in 445 mL at 225 degrees celsius and 1.783 ATM?

the equation you need is PV=nRTP=1.783 atmV=445 mL (convert to L by multiplying by .001)n=moles(what you're looking for)R=.08206T=225 (change Celsius to Kelvin by adding 273)solve for n to get the amount of moles and then multiply the moles by the molar mass of CO2 to get the mass :)


What is the hydrogen-ion concentration if the acid dissociation constant is 0.000 001 and the acid concentration is 0.01 M?

The concentration in such case is calculated including the H ion concentration contributede by water, So the [H] is .00000001+.0000001


What is the pH range of a strong but dilute acid?

It depends on just how dilute it is. If we're talking about a strong acid - in this case, acids like perchloric (HClO4), sulfuric (H2SO4), or nitric (HNO3) - and assume that the acid dissociates completely (an ideal situation; in sulfuric acid's case, only the first proton is assumed to dissociate), the pH of the acid is the negative logarithm of its molarity. For example, if you have 1 × 10-3 M (.001 mol · L-1) hydrochloric acid (HCl), its pH will be -log(1 × 10-3) = 3. (Since real life is a non-ideal situation it will actually be slightly higher, but we can disregard that.) That's the easy part and only applies to strong acids. For other (weak) acids of formula HA ⇌ H+ + A-, the pH is dependent upon the acid dissociation constant pKa, in which case pH = pKa + log([A-]/[HA]). Say you have a weak acid with a pKa of 2.0 and a molarity of .01 M. Since pKa = -log(Ka), that means that Ka = .01. The definition of Ka is [A-][H+]/[HA]. Let's call [A-] and [H+] x for this purpose; this makes [HA] = .01 - x; thus, .01 = x2/(.01 - x). Solving for x gives x2 + .01x - .0001 = 0; using the quadratic formula we get .00618 M. Now we may derive the pH. pH = pKa + log([A-]/[HA]) = 2 + log(.00618/.00382) = 2.21.


What does 14K 001 mean on an engagement ring?

Here "14K 001" would most likely be the note of metal purity and a particular manufacturer's or jeweler's code for identification. "14K" means the purity of the gold is 14 karats, meaning that 58.3% is gold and the rest are other metals. The likely meaning for "001" is a batch number, or could perhaps be a kind of unique identifier that the jeweler or manufacturer uses for inventory or tracking purposes.
