The pH of the finsl solution is equal to <u>2.93</u>
Concentration is the abundance of a constituent divided by way of the overall volume of an aggregate. several sorts of mathematical descriptions may be outstanding: mass concentration, molar concentration, variety concentration, and extent awareness.
C₁ = 0.170 m
V₁ = 17 ml = 0.017 L
C₂ = 0.170 M
V₂ = 22 ml = 0.022 L
C₁V₁ =C₂V₂
0.170× 0.017 L = 2.89 × 10⁻³ ------------- HCl
0.170× 0.022 L = 3.74 × 10⁻³ ------------ NaOH
⇒ 3.74 × 10⁻³ - 2.89 × 10⁻³ = 0.85 × 10⁻³
⇒ 3 + log 0.85
⇒ 3 + -0.07
⇒ pH = <u>2.93</u>
The concentration of an solution is a degree of the amount of solute that has been dissolved in a given amount of solvent or solution. A focused solution is one which has a rather huge amount of dissolved solute.

Answer: 6.77*1022 Molecules
Explanation: :)
There's less space, causing the air particles to collide with the walls of the container more frequently. Pressure is that energy caused by molecules striking a surface. Thus, compacting air molecules leads to higher pressure.
Option B, C and D are correct.
<h3><u>Explanation:</u></h3>
Carbon is a non metallic element with the atomic number 6 and mass number 12. Whereas oxygen is also a non metallic element with the atomic number 8 and mass number of 16.
In carbon monoxide, the mass ratio of oxygen to carbon is 16:12 =1.33. This ratio is same for every sample of carbon monoxide, because carbon monoxide has the universal formula of CO.
Similarly In carbon dioxide , the mass ratio of oxygen to carbon is 32:12 =2.667. This ratio is same for every sample of carbon dioxide, because carbon dioxide has the universal formula of 
.
Even we can see that the mass ratio of oxygen to carbon in carbon dioxide is just twice the mass ratio of oxygen to carbon in carbon monoxide, because of presence of twice as much as oxygen per molecule of carbon dioxide than carbon monoxide.
You should clean up after every investigation because if you leave a mess, maybe another detective will come in and get lost because of the mess you left.
