The relation between density, mass and volume is
1) to calculate = volume
given:
Density = 0.0915 g/ mL
mass = 17.7 grams
formula used:
Thus
Volume 
Answer: 193.44 mL
2) the mass of sample will be
Answer: 7 g
Answer: This was because the experiment showed that a substance could emit radiation even while it was not exposed to light.
Such an object makes a larger dent in the fabric of space-time than an object with little mass. (It has a greater gravitational attraction than less massive objects)
A greater force is required to accelerate such an object than a less massive object
The first element discovered through synthesis was technetium<span>—its discovery being definitely confirmed in 1936. Hope that helps.</span>
