Answer:
Isotopes are variations of chemical elements that have the same number of protons but different number of neutrons.
Explanation:
Answer:
40.3 for the unit that represents the minimum amount of magnesium oxide I beilieve.
Explanation:
Magnesium atoms are heavier than oxygen atoms, so we expect more than 50% of magnesium in the weight composition. Taking just one atom of Mg and one atom of O you will get a mass of 16.0 + 24.3 = 40.3.
Hope this helps! Please tell me if you have any questions :))
V = m / ρ
<span>V = (23,200/8.96) × 1000 </span>
<span>V = 2,589,285.71 mm³ </span>
<span>Now we have volume and given the radius we can solve for its length. </span>
<span>L = V/πr² </span>
<span>L = (2,589,285.71/(π×1.63²))/1×10^6 </span>
<span>L = 0.31 km </span>
<span>So </span>
<span>R = rL </span>
<span>R = 2.061(0.31) </span>
<span>R = .6389 Ω </span>
<span>End.</span>
To solve this equation you use the formula


Plug into the equation

Answer:
0.158L
Explanation:
From the question, we obtained the following information:
C1 = 6.84 M
V1 =?
C2 = 1.84 M
V2 = 588 mL = 588/1000 = 0.588L
Using the dilution formula C1V1 = C2V2. The original volume can calculated for as follows:
C1V1 = C2V2
6.84 x V1 = 1.84 x 0.588
Divide both side by 6.84
V1 =(1.84 x 0.588) / 6.84
V1 = 0.158L
