Answer: Molecular mass of is 82 g
Explanation:
Molecular mass (M) is defined as the mass in grams of 1 mole of a substance.
S.I Unit of Molar mass is gram per mole and it is represented as g/mol.
Atomic Mass of Carbon (C) = 12 g
Atomic Mass of hydrogen (H) = 1 g
Atomic Mass of oxygen (O) = 16 g
Atomic Mass of sodium (Na) = 23 g
Molecular mass of = 12(1)+1(3)+12(1)+16(2)+23(1) = 82 g
The answers for your question is :
Kinetic Energy.
Why?
It’s because they all move
Answer:
2) 0.4 mol
Explanation:
Step 1: Given data
- Volume of the solution (V): 500 mL
- Molar concentration of the solution (M): 0.8 M = 0.8 mol/L
Step 2: Convert "V" to L
We will use the conversion factor 1 L = 1000 mL.
500 mL × 1 L/1000 mL = 0.500 L
Step 3: Calculate the moles of KBr (solute)
The molarity is the quotient between the moles of solute (n) and the liters of solution.
M = n/V
n = M × V
n = 0.8 mol/L × 0.500 L = 0.4 mol
D. No limits on government leadership
A Democratic government sets limits on the amount of power the government has, the people have more power. So free elections, voluntary action, citizen participation; All of these involve democratic things and gives power to the people. No limits on the government leadership would take power from the people, which is unacceptable in a democratic government.
Answer:
True
Explanation:
Hello,
As long as the group VIA elements have 6 valence electrons (electrons at the outermost shell) they just need two electrons to attain the octate, it means that the resulting charge must be -2. In such a way, since VIIA elements have 7 valence electrons, they just need one electron to attain the octate, it means that the resulting charge must be -1.
Best regards.
