Answer: Molar mass of 
is 17.03 g
Explanation:
Molar mass 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.
It is found by adding the atomic masses of all the elements present.
Atomic Mass of Nitrogen (N) = 14.007 g
Atomic Mass of Hydrogen (H) = 1.008 g
Molar mass of = 1(14.007)+3(1.008) g = 17.03 g
Answer:
Because only regular-shaped objects have a consistent length, width, height, and shape.
Explanation:
Because only regular-shaped objects have a consistent length, width, height, and shape. When dealing with an object composed of differing shapes, your must calculate each portion separately and then add them.
Effects of changes in volume in a reversible reaction in a chemical equilibrium can be predicted using Le Chatelier's Principle. I think this might be the answer, I hope it helps.
Answer:
m = 671 grams
Explanation:
Given that,
No of moles, n = 4.9
Molar mass of Barium, M = 137 g
Mass divided by molar mass is equal to no of moles. It can be given by the formula as follows :
or
m = 671 grams
So, the total mass of the sample of Barium is 671 grams.
False
Explanation:
A molecule containing two or more polar bonds in its entire structure is a polar molecule. What determines the polarity of bonds in molecules their net dipole moment.
- In elements combination, the electronegativity difference between two atoms determines polarity.
- In a bonded specie, polarity of a molecule is determined by the net dipole moment.
- The net dipole moment depends on the geometry of the molecule.
- If the geometry favors the formation of polar bonds, the molecule will be polar.
