Answer:
Volume in litter = 0.8 L
Explanation:
Given data:
Mass of KOH = 112 g
Molarity of KOH = 2.5 M
Volume = ?
Solution:
Number of moles of KOH:
Number of moles = mass/ molar mass
Number of moles = 112 g/ 56 g/mol
Number of moles = 2 mol
Volume of KOH:
Molarity = number of moles / volume in litter
Volume in litter = number of moles / Molarity
Volume in litter = 2 mol / 2.5 mol/L
Volume in litter = 0.8 L
<span>In the distant future, earth was no longer habitable by humans due to extreme pollution and excessive waste. Humans were not allowed to go back to earth due to the severity of the planet's condition and they dwell in space for hundreds of years while WALL-E, short for Waste Allocation Load Lifter Earth-class, was the only robot left to clean the planet, little by little.</span>
Answer:
The highest energy level number (1 through 7) for the electrons in an atom corresponds to the period (or row) in the periodic table to which that atom belongs. Because there are 7 periods in the table, there are 7 energy levels. For example, hydrogen (H) is in the first period, so it has only one energy level.
