Answer:

<h3>The answer is 5.0 g/mL</h3>

Explanation:

The density of a substance can be found by using the formula

$density = \frac{mass}{volume} \\$

From the question

mass = 100 g

volume = 20 mL

So we have

$density = \frac{100}{20} \\$

We have the final answer as

Hope this helps you

Answer:

The anions that can act as bases (conjugate bases of weak acids) have the capability to hydrolyse water and produce OH− ions. Cl−, Br−NO−3, SO2−4 are all conjugate bases of strong acids that don't have the capability to hydrolyse water and so they aren't basic.

Answer:

$\boxed{\text{452 mg}}$

Explanation:

(a) Convert pounds to kilograms.

$\text{Mass} = \text{ 166 lb} \times \dfrac{\text{453.59 g}}{\text{1 lb}} \times\dfrac{\text{1 kg}}{\text{1000 g}} = \text{75.30 kg}$

(b) Calculate the dose

$\text{Dose} = \text{ 75.30 kg body mass} \times \dfrac{\text{6.00 mg Elixophyllin}}{\text{1 kg body mass}} = \textbf{452 mg Elixophyllin}\\\text{The dose of Elixophyllin for a 166 lb person is $\boxed{\textbf{452 mg}}$}$
