Answer:

Let's just say that, for whatever reason, you wanted to build your very own live version of Benedict Cumberbatch, from all the chemical elements that make up the British heartthrob. It would cost you precisely $151,578.46 US ($198,166.10 Cdn) — excluding labour, according to author Bill Bryson.

50 ml of 0.2 M acetic acid is shaken with 10 g activated charcoal. The concentration of acetic acid is reduced to 0.5 times the
Olegator [25]

Answer:

0.03 g_{acid}/g_{charcoal}

Explanation:

The amount adsorbed (solute) is the acetic acid, and the adsorbent is the activated charcoal. The mass of the adsorbent is 10 g.

So, we need to calculate the mass of the acetic acid as follows:

m = n*M = C*V*M

Where:

n: is the number of moles = C*V

M: is the molecular mass =  60.052 g/mol

C: is the final concentration of the acid = 0.5*0.2 mol/L = 0.10 mol/L

V: is the volume = 50 ml = 0.050 L

m_{acid} = C*V*M = 0.10 mol/L*0.050 L*60.052 g/mol = 0.30 g

Now, the amount of solute adsorbed per gram of the adsorbent is:

\frac{m_{acid}}{m_{charcoal}} = \frac{0.30 g}{10 g} = 0.03 g_{acid}/g_{charcoal}

Therefore, the amount of solute adsorbed per gram of the adsorbent is 0.03 g/g.

I hope it helps you!

An object has a density of 20.00 g/mL. If the object has a volume of 50.00 mL, what is its mass?
LuckyWell [14K]

Answer:

<h3>The answer is 1000 g</h3>

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

<h3>mass = Density × volume</h3>

From the question

volume of object = 50 mL

density = 20 g/mL

We have

mass = 20 × 50

We have the final answer as

<h3>1000 g</h3>

Hope this helps you
