Answer:

The answer to your question is 25 grams

Explanation:

Data

half-life = 5730 years

sample = 200 g

after 3 half-lives

Process

Calculate the amount of sample after one, two and three half-lives.

After each half-life, that of sample is half the previous amount.

                         Number of half-lives           Amount of sample

                                       0                                        200 g

                                        1                                         100 g

                                        2                                          50 g

                                       3                                           25 g

For an ideal gas under constant volume, if the pressure is tripled, what happens to the Kelvin temperature?
EleoNora [17]

Answer:

Increase pressure 3X => increase Temperature 3X

Explanation:

Gay-Lussac Law => T ∝ P => T =kP => Empirical Relationship => T₁/P₁ = T₂/P₂  

=> T₂ = T₁P₂/P₁

Given P₂ = 3P₁ => T₂ = T₁(3P₁)/P₁ = 3T₁
