The block of iron metal with a density of 7.87 g/mL has a volume in mL of 0.2414 mL
The density formula and the procedure we will use is:
ρ = m/v
Where:
- v= volume
- ρ= density
- m= mass
Information about the problem:
- m= 1.90 g
- ρ= 7.87 g /mL
- v= ?
Applying the density formula and clearing the volume (v), we get:
ρ = m/v
v = m / ρ
v = 1.90 g / 7.87 g/ mL
v = 0.2414 mL
<h3>What is density?</h3>It is a physical quantity that expresses the ratio of the body mass to the volume it occupies.

Answer:
its mass
its temperature
Explanation:
The heat capacity of a body is the amount of heat needed to raise that temperature of a body by 1k or 1°C.
It is expresses as:
H = m c Ф
where m is the mass of the body
c is the specific heat of the body
Ф is the temperature change of the body
Specific heat capacity is that heat content needed to raise the temperature of a unit mass of a substance by 1k or 1°C
Heat capacity is also known as heat content;
To solve the problem:
since H = m c Ф
we make the unknown c the subject of the expression;
c = = H / mФ
So to obtain the specific heat capacity, divided the heat capacity by mass and its temperature change.
