Answer:
4.49 g
Explanation:
To find the mass of water, you need to use the following equation:
Q = mcΔT
In this equation,
-----> Q = energy (J)
-----> m = mass (g)
-----> c = specific heat (J/g°C)
-----> ΔT = change in temperature (°C)
You can plug the given values into the equation and solve for "m".
Q = 1,500 J c = 4.18 J/g°C
m = ? g ΔT = 113°C - 33°C = 80°C
Q = mcΔT <----- Specific Heat Equation
1,500 J = m(4.18 J/g°C)(80°C) <----- Insert values
1,500 J = m(334.4) <----- Multiply 4.18 and 80
4.49 = m <----- Divide both sides by 334.4
