A solution has a hydrogen ion (or hydronium ion) concentration of 3.16×10−9M.
mel-nik [20]

pH = 9.5

Explanation:

We know that the hydronium ion concentration is [H₃O⁺] = 3.16 × 10⁻⁹ M.

The formula for pH is:

pH = -lg[H₃O⁺]

We input the known values to find the pH:

pH = -lg[3.16 × 10⁻⁹]

pH = 9.5

Why do roads have speed limits rather than velocity limits
Igoryamba
Speed is the rate at which something goes, and velocity is the average acceleration, which means a car can go slow for a bit, and fast for a bit, and have a velocity of medium. Also, speed is much easier to measure.

Explain step by step, please!
konstantin123 [22]

Answer:

10. Stacey

11. 7.86 g/cm^3 (3dp)

OR 786 kg/m^3 (SI units)

Explanation:

10. The correct exact answer for 10 is 26.169 (6.71x3.9). While Sam was correct in the precision of the number (2dp just like the given measurements), he was incorrect in the number itself. While Stacy's number was not as precise as Sam's (0dp), it is correctly rounded to the nearest whole number, therefore Stacy is correct.

11. The formula for density is mass/volume. The mass here is 264g and the volume is 33.6ml, therefore the density is 7.86 (3 sig figs because given values had 3) g/cm^3, because the mass was given in grams and 1ml = 1cm^3. Converted to SI units it is 786 kg/m^3.

Hope this helped!
