Concentration of Ba2+ is 1.00 mol/dm3 or 1M
lets work back. The formula to find density is d= m/v. fill in the values you know.
10 = 500/v
well, we don't need to use a calculator. dividing by ten is going to the left once, and removing one value of ten.
this means you have a volume of 50.
Hope this helps! :D
Answer:
is there a picture of the problem
Explanation:
Answer:
36.2 K
Explanation:
Step 1: Given data
- Initial pressure of the gas (P₁): 8.6 atm
- Initial temperature of the gas (T₁): 38°C
- Final pressure of the gas (P₂): 1.0 atm (standard pressure)
- Final temperature of the gas (T₂): ?
Step 2: Convert T₁ to Kelvin
We will use the following expression.
K = °C +273.15
K = 38 °C +273.15 = 311 K
Step 3: Calculate T₂
We will use Gay Lussac's law.
P₁/T₁ = P₂/T₂
T₂ = P₂ × T₁/P₁
T₂ = 1.0 atm × 311 K/8.6 atm = 36.2 K
Jamal’s hair is behaving that way because he is in a cold area.
