The dimensions of room are . Thus, volume of room will be:
Converting to
Since,
Thus,
Now, concentration of carbon monoxide in the urban apartment is , thus, mass of carbon monoxide can be calculated as follows:
Rearranging,
Putting the values,
converting
Since, thus,
Therefore, mass of carbon monoxide present in the room is .
Chemical senses require moisture, or water, for transduction to occur.
Scientists are able to understand Earth's interior by studying seismic waves. These are waves of energy that travel through Earth, and they move similarly to other types of waves, like sound waves, light waves, and water waves.
Answer:
150 mL
Explanation:
From the question given above, the following data were obtained:
Molarity of stock solution (M₁) = 10 M
Volume of diluted solution (V₂) = 3 L
Molarity of diluted solution (M₂) = 0.5 M
Volume of stock solution needed (V₁) =?
The volume of stock solution needed can be obtained as follow:
M₁V₁ = M₂V₂
10 × V₁ = 0.5 × 3
10 × V₁ = 1.5
Divide both side by 10
V₁ = 1.5 / 10
V₁ = 0.15 L
Finally, we shall convert 0.15 L to mL. This can be obtained as follow:
1 L = 1000 mL
Therefore,
0.15 L = 0.15 L × 1000 mL / 1 L
0.15 L = 150 mL
Therefore, the volume of the stock solution needed is 150 mL
