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:
The answer to your question is: letter c
Explanation:
Data
V1 = 612 ml n1 = 9.11 mol
V2 = 123 ml n2 = ?
Formula


n2 = 1.83 mol
If CFC increases, there will be a ozone depletion ! the UV rays starts entering and leads to mutation and deaths !
the temperature of the climate increases drastically !
The specific gravity of the solution is 1.07, which contains 5.34g for a 5.00ml sample.
Density of a substance is
Density = Mass / Volume
= 5.34/5
= 1.07
Density of water = 1
Specific gravity = Density of substance/density of solvent
Specific gravity = 1.07 / 1
Specific gravity = 1.07
Specific gravity, often known as relative density, is the ratio of a substance's density to that of an industry standard.
If a material has a relative density that is less than 1 compared to the reference, it is less dense than the reference; if it is larger than 1, it is denser. Identical volumes of the two substances have the same mass if the relative densities are equal, or exactly 1.
