Answer:
133.3atm
Explanation:
Given parameters:
Initial volume = 400ft³
Final volume = 3ft³
Initial pressure = 1atm
Unknown:
Final pressure = ?
Solution:
To solve this problem, we apply Boyle's law which states that "the volume of a fixed mass of a gas varies inversely as the pressure changes if the temperature is constant".
Mathematically;
P₁V₁ = P₂V₂
P and V are pressure and volume
1 and 2 are initial and final states;
Insert parameters and solve;
1 x 400 = P₂ x 3
P₂ = 133.3atm
B is the correct answer! I learned this in class last week :)
Answer:You can view more details on each measurement unit: molecular weight of BaCl2 or grams This compound is also known as Barium Chloride. The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles BaCl2, or 208.233 grams.
Explanation:
1 mol Au ---------------- 196.9665 g
0.150 mol Au ----------- ?
0.150 x 196.9665 / 1
= 29.54 g
hope this helps!
