Answer:
C₆H₈O₇ = 192 g/mol
Explanation:
Molar mass is the sum of the atomic weight of the atoms present in compound.
Formula of citric acid:
C₆H₈O₇
Atomic weight of hydrogen = 1 amu
Atomic weight of carbon = 12 amu
Atomic weight of oxygen = 16 amu
C₆ = 6 × 12 = 72 g/mol
H₈ = 8 × 1 = 8 g/mol
O₇ = 7 × 16 = 112 g/mol
C₆H₈O₇ = 72 g/mol + 8 g/mol + 112 g/mol
C₆H₈O₇ = 192 g/mol
A metallic bond is a force that holds atoms together in a metallic substance.
The answer is A. As the first statement is a true statement. Hope this help you
Answer:
Solids, liquids, and gases are made of tiny particles called atoms and molecules. In a solid, the particles are very attracted to each other. They are close together and vibrate in position but don't move past one another. In a liquid, the particles are attracted to each other but not as much as they are in a solid.
Answer:
Biosphere
Explanation:
