How many milliliters of 2.0 M NaCl solution would you need to make 250 ml of 0.15 M solution​

Chemistry
1 answer:
Stells [14]3 years ago
5 0

Answer:

18.75 mL of NaCl solution is required.

Explanation:

Given data:

Molarity of solution one = 2.0 M

Volume of solution one = ?

Molarity of second solution = 0.15 M

Volume of second solution = 250 mL

Solution:

M₁V₁ = M₂V₂

V₁ = M₂V₂/M₁

V₁ = 0.15 M × 250 mL /  2.0 M

V₁ = 37.5 M.mL /  2.0 M

V₁ = 18.75 mL

When magnesium hydroxide reacts with nitric acid, it produces magnesium nitrate and water.
mezya [45]

Answer:

The law of conservation of mass states that mass is neither created nor destroyed but the mass of the system must remain constant over time. The total number of atoms in the reactants is equal to the total number of atoms in the product. Therefore, this chemical equation shows that energy is conserved and demonstrates the law of conservation of mass.

Rank these systems in order of decreasing entropy. 1 = Greatest entropy and 7 = Least entropy. Group of answer choices 1 mol of
AlladinOne [14]

Answer:

  1. 1 mole of carbon disulfide gas at 273 K and 40 L
  2. 1 mol of chlorine gas at 273 K and 40 L
  3. 1 mol of neon gas at 273 K and 40 L
  4. 1 mol of neon gas at 273 K and 20 L
  5. 1/2 mol of neon gas at 273 K and 20 L
  6. 1/2 mol of neon gas at 100 K and 20 L
  7. 1/2 mol of liquid neon at 100 K

Explanation:

Entropy is the measure of disorder or randomness in a closed system. Its an extensive property of a thermodynamic system

The following points must be considered when ranking the systems according to their entropy:

  1. The entropy of gases are highest than liquids or solid. And entropy of liquid is higher than solid. That is because gas has more microstate thus have the highest entropy.
  2. Entropies of large complicated molecules are greater than those of smaller, simpler molecules. Because larger molecules have more disorder because of the greater number of ways they can be move around in three dimensional space.
  3. highest temperature and highest volume will lead to greatest entropy
  4. 1 mole of any substance will have greater entropy than 1/2 mole of that same substance
