Answer:
0.48 mols
Explanation:
to convert moles to mass u need to divide mass by the molar mass of NaCl which is 58.44g/mols.
28g ÷ 58.44g/mol = 0.48 mols
Answer:
Ionic solids
Explanation: Ionic solids—Made up of positive and negative ions and held together by electrostatic attractions. They're characterized by very high melting points and brittleness and are poor conductors in the solid state. An example of an ionic solid is table salt, NaCl.
Specific gravity = (density of substance)/(density of water)
= (1.18 g/mL)/(1.00 g/mL) = 1.18
Heat death refers to the 2nd law of thermodynamics which states that entropy trends increases in an isolated system. Thus hypothesized that the universe would last for an amount of time enough until it reaches a state that all energy is equally distributed.
