Lithium is a metal and Fluorine is a non-metal, which means they will form an ionic bond. An ionic bond is when a metal atom donates its electron complete to a non-metal atom.
The density of the object is 1.96 g/cm³.
Mass = 73.5 g
Volume = 82.5 mL – 45.00 mL = 37.5mL = 37.5 cm³
Density = mass/volume = 73.5 g/37.5 cm³ = 1.96 g/cm³
The chemical bonds in CH4 are all single bonds. C only can bond 4 times because it needs 8 electrons in it's outer shell and only has four right now. The bonds represented are all single bonds because there are two electrons present on each side of the carbon. Two electrons, in this case, equals one bond.
Answer:
1.878g
Explanation:
Volume = 30.0ml
Density = 0.626gcm−3
Mass = ?
Be careful in this kind of questions to check for the units. In this case one has to remember 1 mL equal 1 cm³ so density = 0.626g/ml
The relationship between all three parameters is given by the equationn below;
Mass = Density * Volume
Mass = 0.626g/ml * 30 = 1.878g
