The molarity of the diluted solution is 0.32 M
Considering the question given above, the following data were obtained:
Volume of stock solution (V₁) = 500 mL
Molarity of stock solution (M₁) = 2.1 M
Volume of diluted solution (V₂) = 3.25 L = 3.25 × 1000 = 3250 mL
<h3>Molarity of diluted solution (M₂) =....? </h3>
The molarity of the diluted solution can be obtained as follow:
<h3>M₁V₁ = M₂V₂</h3>
2.1 × 500 = M₂ × 3250
1050 = M₂ × 3250
<h3>Divide both side by 3250</h3><h3 />
M₂ = 1050 / 3250
<h3>M₂ = 0.32 M</h3>
Therefore, the molarity of the diluted solution is 0.32 M

Answer: 360 minutes are required for 20 percent of a sample of cyclopropane to isomerize topropane.
Explanation:
Half life is the amount of time taken by a radioactive material to decay to half of its original value.
As the units of rate constant is , the reaction follows first order kinetics.
Expression for rate law for first order kinetics is given by:
where,
k = rate constant =
t = time for decomposition = ?
a = let initial amount of the reactant = 100
x = amount decayed =
a - x = amount left after decay process = 100-20= 80
Thus 360 minutes are requiredfor 20 percent of a sample of cyclopropane to isomerize topropane.
Molecular weight of (NH4)2 CO3 = 96 gm. 96 gm (NH4)2CO3 = 1 mol of (NH4)2CO3 = 2 moles of NH4.
Therefore 1.3 gm of (NH4)2CO3 = 1.3x2/ 96 = 0.027 moles.
Answer:
water can get bigger and make it a different shape.
Explanation:
it can get bigger and the water can add up to make it a different shape i think i am sorry if its wrong tho
