Answer:
The answer to your question is: Volume = 29.79 cm³
Explanation:
Data
Density of gold = 19.3 g/cm3
Mass = 575 grams
Formula
density = mass / volume
Volume = mass/density
Volume = 575 g / 19.3 g/cm3
Volume = 29.79 cm³
Answer:
A molecular formula tells us what atoms and how many of each type of atom are present in a molecule.
Explanation:
If only one atom of a specific type is present, no subscript is used.
For atoms that have two or more present, a subscript is written after the symbol for that atom.
Molecular formulas do not indicate how the atoms are arranged in the molecule.

Answer:Low temperatures
Explanation:
∆G= ∆H-T∆S
If ∆H is negative (exothermic reaction), then in order to maintain ∆G<0 which is the condition for spontaneity; T must decrease. This is because, decrease in T will keep the difference of ∆H and T∆S at a negative value in order to satisfy the above stated condition for spontaneity.
by making sure they are in the lowest ratio. by adding them to see if they total 100. by checking that they are whole-number multiples. by dividing them by the molar mass.
with his well-known gold foil experiment in which he demonstrated that the atom has a tiny and heavy nucleus.
