Assuming that the number of mols are constant for both conditions:
Now you plug in the given values. V_1 is the unknown.
Separate V_1
V= 162.782608696 L
There are 2 sig figs
V= 160 L
Answer:
Theoretical yield = 3.75g
Explanation:
Percent yield is defined as one hundred times the ratio between actual yield and theoretical yield. The expression is:
Percent yield = Actual Yield / Theoretical Yield * 100
In the problem, your actual yield was 3-00g.
Percent yield is 80.0%.
Solving for theoretical yield:
80% = 3.00g / Theoretical yield * 100
Theoretical yield = 3.00g / 80.0% * 100
<h3>Theoretical yield = 3.75g</h3>
Answer:
69.152 % → 63Cu
30.848 % → 65Cu
Explanation:
As you know, the average atomic mass of an element is determined by taking the weighted average of the atomic masses of its naturally occurring isotopes.
Answer Electromagnetic waves are used to transmit long/short/FM wavelength radio waves, and TV/telephone/wireless signals or energies. They are also responsible for transmitting energy in the form of microwaves, infrared radiation (IR), visible light (VIS), ultraviolet light (UV), X-rays, and gamma rays.
Explanation:
1) Chemical equation of the equilibrium
BaCrO4⇄ Ba (2+) + CrO4 (2-)
2) Ksp equation
Ksp = [Ba(2+)] [CrO4 (2-)]
where Ksp = 1.0 * 10^ - 10 and [Ba(2+)] = [CrO4(2-)] = x
3) Calculations
1.0 * 10^ -10 = x * x
=> x^2 = 1.10 * 10^-10
=> x = √[1.0 * 10^ -10] = 0.000010
Answer: [Ba(2+)] = [CrO4(2-)] = 0.00001 M
