Liquid water turning into vapor.
The process in which the concentration of the solution is lessened by the addition of water is said to be dilution and equation of dilution relates the initial concentration and volume of stock solution with the final concentration and volume of the solution.
Formula is given by:
(1)
where,
is the initial concentration
is the initial volume
is the final concentration
is the final volume
Now,
= 0.850 M
= 4.12 L
=?
= 10.00 L
Substitute the give values in formula (1),
= 
Thus, the final concentration of the
solution =
Answer:
V₂ = 22.23 mL
Explanation:
According to general gas equation:
P₁V₁/T₁ = P₂V₂/T₂
Given data:
Initial volume = 25 mL
Initial pressure = 725 mmHg (725/760 =0.954 atm)
Initial temperature = 20 °C (20 +273 = 293 K)
Final pressure = standard = 1 atm
Final temperature = standard = 273.15 K
Final volume = ?
Solution:
P₁V₁/T₁ = P₂V₂/T₂
V₂ = P₁V₁ T₂/ T₁ P₂
V₂ = 0.954 atm × 25 mL × 273.15 K / 293 K × 1 atm
V₂ = 6514.63 mL . atm . K / 293 K . atm
V₂ = 22.23 mL
The question is incomplete, the complete question is;
the element vanadium is a solid at room temperature, and its density is 6110 kilograms per meter cubed. its melting point is 1910 degrees celsius.” which correctly evaluates the statement? not reliable because opinions are presented, reliable because testable facts are presented, not reliable because it is very brief ,reliable because metric units are used
Answer:
reliable because testable facts are presented
Explanation:
Science is a body of knowledge that deals with testable facts. Science is highly empirical and any superstitious proposition is quickly discarded as nonsense.
The statement, ''The element vanadium is a solid at room temperature, and its density is 6110 kilograms per meter cubed. Its melting point is 1910 degrees Celsius" presents facts that can be verified by laboratory investigation.
Hence we can conclude that the given statement is reliable because it contains testable facts.
