A mass of 2 g burning bread heats up 80 g of water from 21 C to 80 C, Calculate the amount of heat transfered to water ( given that = 4.2 j/gC) *

Using dilution equationm1v1 =m2v2 ; where m1 and m1 are the intiial and final concentration, and v1 and v2 are the initial and final volume.5  × 5 m = 8 l  × m2m2 = 25/8 = 3.125 mtherefore; the resulting molarity is 3.125 m
