The density of the object is 5 g/cm
<span>.068443 mol/L
First we must find the molar mass of NaCl. We find the atomic mass of sodium and chlorine and add them:
Na: 22.9898
Cl: 35.453
22.9898 + 35.453 = 58.4428g/mol
The we find the number of mols contained in 400mg of NaCl:
.4g / 58.4428g/mol
.0068443 mol
Since 100mL is a tenth of a liter we can multiple the number of mols by ten:
.068443 mol/L</span>
Answer:
6
Explanation:
The maximum number of electrons in the orbitals of sub-levels are given as:
for s-sublevel we have two electrons and one orbital
p-sublevel we have six electrons and three orbitals
d-sublevel we have ten electrons and five orbitals
f- sublevel we have fourteen electrons and seven orbitals
The second energy level is represented by the p-sub-level and it will accommodate 6 electrons.
Yes, The car will accelerate if its velocity changes in magnitude, in direction, or both. If a car is traveling at a constant speed of 35 m/s, it can be accelerating if its direction of motion is changing.
