Answer:
New pressure = 42216.66 Pa
Explanation:
Given that,
Initial volume, V₁ = 5 m³
Final pressure, P₁ = 101320 Pa
Final volume, V₂ = 12 m³
We need to find the final pressure of the gas. We know that the relation between pressure and volume is given by :
So, the new pressure is equal to 42216.66 Pa.
The endocrine system is important to the function of the human body because, endocrine glands release hormones into the bloodstream. Which lets the hormones travel to the cells in other parts of the body. This also helps control mood, growth and development, the way our organs work, metabolism and reproduction.
Covalent bonds and it is between the hydrogens (hydrogen bonds)
Answer:
The molarity of this KOH solutions 3.21 mol / L (option C is correct)
Explanation:
Step 1: Data given
Mass of KOH = 45.0 grams
Molar mass of KOH = 56.1 g/mol
Volume = 250.0 mL = 0.250 L
Step 2: Calculate moles KOH
Moles KOH = mass KOH / molar mass KOH
Moles KOH = 45.0 grams / 56.1 g/mol
Moles KOH = 0.802 moles
Step 3: Calculate molarity
Molarity KOH solution = moles KOH / volume water
Molarity KOH solution = 0.802 moles / 0.250 L
Molarity KOH solution = 3.21 mol / L
The molarity of this KOH solutions 3.21 mol / L (option C is correct)
