Answer: 0.048 kPa
Explanation: no clue i just looked it up you’re welcome y’all:)
Using the titration formula, we know that:
(2.0 M)(volume of acid)=(3.0 M)(250 mL)
volume of acid = (3.0)(250)/(2.0) = 375 mL
Answer:
The environment Ecosystems are also affected by climate change. Habitats are being modified, the timing of events such as flowering and egg laying are shifting, and species are altering their home ranges. Changes are also occurring to the ocean.
Explanation:
Answer:
66.0 atm
Explanation:
We can calculate the osmotic pressure (π) using the following expression.
where,
Step 1: Calculate i
Sodium sulfate completely dissociates according to the following equation.
Na₂SO₄ ⇒ 2 Na⁺ + SO₄²⁻
Since it produces 3 ions, i = 3.
Step 2: Calculate M
We can calculate the molarity of Na₂SO₄ using the following expression.
Step 3: Calculate T
We will use the following expression.
K = °C + 273.15
K = 20°C + 273.15 = 293 K
Step 4: Calculate π
