Remembwer pH is = the negative logarithm to base ten, of the hydrogen ion concentration .
So with a concentration of 0.001 M
The hydrogen ion concentration is 0.001 = 10^(-3)
ph = -log(10)[H^+]
pH = -log(10)10^-3
pH = -(-3) log(10)10 ( Remember log(10)10 = 1 )
pH = -(-3)(1) = --3 = 3
pH = 3
-log(0.001)
= a pH of 3
The answer is 4 - .0001 equals 1X10 -4 which equals a pH of 4
There wasn't enough room to write everthing I wanted to say, but I tried it on my own and this is what I was able to come up with: [C] = .3646 mg/ml HCl HCl = 36.46 grams per mole *convert to g/L* .3646mg/1ml X 1g/1000mg X 1000ml/1L = .0003646g/L *convert g/L to Moles/L* [C] = .0003646g/1L X 36.46g/ 1M = .0001 M/L Am I correct?
3. since the [H+]=0.001 M then pH= -log[H+] -log(0.001)=3 pH=3.
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.
According to scientists, Krypton was initially discovered by William Ramsey while conducting experiments with liquid gasses in London in 1898. Krypton is naturally found in the earthâ??s crust.

They're equal.
Kilo stands for thousand 1Meter=.0001 kilometers
There are 1000 milligrams in a gram. Milligrams is written as .0001. So 250 milligrams is equal to .25 grams.
30 * 0001 = 30
1 millimeter is equal to .0001 meters * * * * * Actually, 1000 millimetres = 1 metre so that 1 mm = 0.001 metre.

01 January 0001 was a Saturday.
0001 = 12:01 AM
For Capital A, 0100 0001. For Lowercase A, 0110 0001.
The answer is 4 - .0001 equals 1X10 -4 which equals a pH of 4
