The weight is influenced by the density and the volume. In this case, you are given the density of gasoline(0.65g/ml) and the volume (31l or 8 gallons). Since the unit is different, that mean you need to convert it. It will be easier to convert liter into ml than gallon so we will use 31L as volume. The calculation would be:
mass=density * volume= 0.65g/ml * 31l * (1000ml/l) * (1kg/1000gram)= 20.15kg
Explanation:
If a body reflects only a/few color/s of the visible spectrum by absorbing remaining, it appears in that reflected color/s. In case of water, its tri-atomic (2 atoms of hydrogen and one atom of oxygen) structure does not absorb any colors from the visible spectrum of the light. ... Hence water appears colorless while others do absorb

Explanation:
a. Molar Mass = ∑Atomic Masses = 12C + 22H + 11O = 12(12) + 22(1) + 11(16) = 144 + 22 + 176 = 342 g/mole
b. For 100ml of 0.10M solution => Molarity x Volume (liters) = moles needed x mole weight = grams solute needed for 100ml solution. This can be given by the expression ...
mass solute needed (g) = Molarity needed x Volume needed in liters x mole wt of solute = (0.10M)(0.100L)(342g/mole) = 3.42 grams solute.
mixing => Transfer 3.42 grams of solute (C₁₂H₂₂O₁₁) into mixing container and add solvent (water) up to but not to exceed 100 ml total volume.
c. mass needed for 100ml of 0.50M solution = M·V·f.wt. = (0.50M)(0.100L)(342g/mole) = 1.71 grams solute. => mix as in 'b'.
Answer:
No. Two atoms of the same chemical element are typically not identical. Since the states of the electrons in an atom are what determine the nature of the chemical bonding that the atom experiences, two atoms of the same element can react differently if they are in different states.
Vibration?
I’m not super sure.
