it says to redeem when prompted to when i sign in but nothing so far can i just redeem it any time? (btw im asking because i dont want to ruin anything and redeem it at the wrong time or my xbox will blow up something worse!)

i don't mean angelina jolie's daughter Zahara

what i mean is their parents tried to abort them but they ended up surviving.

1. What would the pH of a solution be if the [H+] = 3.00 x 10-5 moles/liter?

2. What would the pOH of a solution be if the [H+] = 3.00 x 10-5 moles/liter?

3. If a solution had an [OH-] = 3.00 x 10-10 moles/liter, what would be the pH value of this solution?

4. If the pH value was 3.6, what is the [H+]? (10n = en)

1. Whats' the atomic mass in grams of 0.35 moles of CH4?

2. How many grams of CO are in 125 ml of a 0.25 molal solution

3. Calculate the number of molecules in 0.75 moles of CH4

4. Potassium fluoride (KF), a salt, has a molecular weight of 58.10 grams. How many grams would be needed to make 1.0 liter of 5.0 molar salt solution

5. Potassium fluoride (KF), a salt, has a molecular weight of 58.10 grams. How many grams would be needed to mix 1.0 liter of 0.10 M salt solution?
