Mass of water : 30.83 g

Further explanation  

Heat can be calculated using the formula:  

Q = mc∆T  

Q = heat, J  

m = mass, g  

c = specific heat, joules / g ° C  

∆T = temperature difference, ° C / K  

  • ∆T = temperature difference

[tex]\tt \Delta T=T_f(final)-T_i(initial)\\\\\Delta T=98-45=53^oC[/tex]

  • mass of water

[tex]\tt m=\dfrac{Q}{c\times \Delta T }\\\\m=\dfrac{6830}{4.18\times 53}\\\\m=30.83~g[/tex]
