Pressure since pressure is defined as force per unit area and the molecules exert a force on the walls of the container when they bombard it
Cm^3 = mL
1.11 g/cm^3 = 1.11 g/mL
Density (g/mL) multiplied by volume (mL) will give us the mass (g)
1.11 g/mL * 387 mL = 429.57 g
And since we have 3 significant figures, we have 430. g.
DNA is an evolutionary clock that's extremely useful in our lives because it mutates. The mutations that occur in our DNA causes the organisms to diverge evolutionarily from one another, providing us our natural clock in the timeline of evolution.
Answer :electrostatic repulsion.
EXPLANATION
Valence shell electron pair repulsion theory, or VSEPR theory, is a model used in chemistry to predict the geometry of individual molecules from the number of electron pairs surrounding their central atoms
0.80M = x/1.5L
x = 1.2 moles
1.2 moles of Na is about 27.6 grams of Na
