Answer:
Density, 
Explanation:
It is given that, placing a sample of iron (II) oxide into a graduated cylinder makes the water volume increase 12.0 mL.
It means that the volume of the sample is 12 mL
The weight of the sample is 76.6 g
We need to find the density of the sample.
12 mL = 12 cm³
The formula of density is given by :
So, the density of the sample is 
.

Answer:
The Curies established that radioactivity is a property of an atom that does not change if changes occur to the physical or chemical properties of the atom.
and
Hans Geiger invented a method for detecting and measuring radioactivity.
Explanation:
i just did it rn
Mass = 63.5 grams
density = 0.818 g/mL
D = m / V
0.818 = 63.5 / V
V = 63.5 / 0.818
V = 77.628 mL
hope this helps!
