Taking into account the definition of calorimetry, the mass of the coffee is 253.33 g.
<h3>Calorimetry</h3>
Calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.
Sensible heat is defined as the amount of heat that a body absorbs or releases without any changes in its physical state (phase change).
So, the equation that allows to calculate heat exchanges is:
Q = c× m× ΔT
where:
- Q is the heat exchanged by a body of mass m.
- c is the specific heat sudstance.
- ΔT is the temperature variation.
<h3>Mass of coffee</h3>
In this case, you know:
- Q= 190 calories
- c= 1
- m= ?
- ΔT= 0.75 C
Replacing in the equation that allows to calculate heat exchanges is:
190 cal = 1 × m× 0.75 C
Solving:
m= 190 cal÷ (1 × 0.75 C)
<u><em>m=253.33 g</em></u>
Finally, the mass of the coffee is 253.33 g.
