7.55 x 6.02 x 10²³ = 4.55 x 10²⁴ atoms
Answer:
2.5 g
Explanation:
I may have misunderstood the question but if there is 10mg of a substance per mL, and there is 250mL, the total would be 10 x 250 = 2500mg = 2.5 g
Answer:

Answer:
Ideal / Perfect <span>gas follows all of the gas laws.
Explanation:
Those gases which obeys Ideal gas equation are known as Ideal gases. The Ideal gas equation is a combination of all gas laws including Boyle's Law, Charle's Law and Avogadro's Law, it is mathematically expressed as
P V = n R T
Ideal gases are termed as those gases in which the intermolecular forces are negligible, therefore, these gases doesn't interact with each other.
On the other hand, real gases can be made ideal by increasing temperature and decreasing pressure.</span>
C₁ * V₁ = C₂ * V₂
1.0 * 20 = C₂ * 60
20 = C₂ * 60
C₂ = 20 / 60
C₂ = 0.33 M
hope this helps!
