Answer:
15g
Explanation:
Molar mass of acetic acid = 60g/mol
Molarity = mass ÷ molar mass
mass = 0.25 × 60
= 15g
∴ 15g of acetic acid weighed into 1L volumetric flask would give 0.25M of acetic acid.
<em>Alternatively, if the solution is being prepared from a stock solution of known concentration, (say 500mL of 0.5M solution), the formular C2V1 =C2V2 can be used to find the dilution volume.</em>
The Juan de Fuca plate is at a subduction zone which can only occur at a convergent boundary.

Heterogeneous mixtures are made of different substances that remain physically seperate. An example would be mixing sand and sugar together.
the answer would be soil
The answer is B soil
A rate law or rate equation expresses the relationship between the <u>concentration rate</u> of a reaction and the <u>rate</u> of the reactants.
<h3>What is the rate law?</h3>
Rate law states the dependency of the rate of a reaction on the concentration of the reaction. Rate law is calculated by the difference in molar concentration of the reaction.
Thus, the correct options are <u>concentration rate </u>and<u> rate</u> of the reactants.

According to avogadro constant, the number of units in one mole of any substance contain 6.022 x10 ^23 atoms
therefore the number of o atoms in one mole of CuSO4 = 6.022 x 10 ^ 23
