Answer:
1569 torr
Explanation:
Assuming ideal behaviour and constant temperature, we can solve this problem by using <em>Boyle's law</em>, which states:
Where in this case:
We <u>input the data given by the problem</u>:
- 202 mL * 505 torr = 65.0 mL * P₂
And <u>solve for P₂</u>:
Answer:
The correct option is GRADUATED CYLINDER.
Explanation:
Each of the glassware used in the laboratory has its specific functions. The graduated cylinder is especially manufacture to facilitate the measurement of accurate volume of liquids in the laboratory. Measurements obtained by means of graduated cylinder can be considered to be moderately accurate; volumentric flasks are more accurate than graduated cylinder and should be used when higher precision are required.
Yes the particles are larger than 10,000 Angstroms which allow it to be separated by filtration
Answer:
There are 
grams contained in all the seawater in the world.
Explanation:
At first let is determinate the total mass of seawater (
), measured in grams, in the world by definition of density and considering that mass is distributed uniformly:
Where:
- Density of seawater, measured in grams per liters.
- Volume of seawater, measured in liters.
If 
and 
, then:
The total mass of sodium chloride is determined by the following ratio:
Given that and 
, the total mass of sodium chloride in all the seawater in the world is:
There are grams contained in all the seawater in the world.
Answer:
greenhouse effects are molecules that trap heat on earth atmosphere
