What is the [OH-] of a substance that has a pH of 11?

Deffense [45]

Answer:

0.001 M OH-

Explanation:

[OH-] = 10^-pOH, so

pOH + pH = 14 and 14 - pH = pOH

14 - 11 = 3

[OH⁻] = 10⁻³ ; [OH-] = 0.001 M OH-

Evaluate (714 mm )/(37 s ) to three significant figures and express answer in si units using an appropriate prefix.

romanna [79]

The SI base units for length is meter (m) and for time is seconds (s).

The given ratio is $\frac{714 mm}{37 s}$

$\frac{714 mm}{37 s} = 19.297 mm/s \simeq 19.3 mm/s$

Converting mm/s to m/s as:

Since, 1 mm/s = 0.001 m/s

So, $19.3 mm/s = 0.0193 m/s$

Since, zeroes to the left side of the non-zero number are not significant hence, the evaluation of $\frac{714 mm}{37 s}$ to three significant figures and answer in SI units is $0.0193 m/s$ .
