Density is calculated as mass divided by volume. We are given the mass of 15.0 grams, so we need to find the volume. For a cube, volume is calculated as (length of side)^3, so in this case, we have the length of a side as 44.5 mm, which is equivalent to 4.45 cm.
Volume = (4.45 cm)^3 = 88.1 cm^3
Then we divide mass by the volume:
Density = (15.0 grams) / (88.1 cm^3) = 0.170 g/cm^3
So the correct answer is A.
The balanced equation for the half reaction that occurs in basic solution is
Bothe the right and left side of the equation has an equal number of electrons and equal number of elements.
Answer:
sugars such as dextrose and sucrose increase the surface tension of water. The effect was interpreted as a depletion of the solute molecules from the water-air interface.
