ANSWER: 15N

WORKING OUT:

The gravitational field strength on Earth is 10N per kg.

Therefore, we can work out the weight of the book by multiplying the mass of the book by the number of newtons per kilogram on earth.

1.5 times 10 = 15N

This is how we can conclude with the answer, "15N".

You have OH- conc = </span>2.3 ✕ 10−6 m
From the formula, you can observe the ratio of Cu2+ to OH- is 4 : 6 = 2:3

So, for 2.3 ✕ 10−6 m OH-
[Cu2+] = $\frac{2}{3} \times 2.3 \times 10^{-6}$

$= 1.53 \times 10^{-6}
