Mass of water = 8.84 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
c of water = 4.182 J / g ° C
Q = 925 J
mass of water :
[tex]\tt Q=m.c.\Delta T\\\\925=m\times 4.182\times (40-15)\\\\m=8.84~g[/tex]
