Answer
a) 2.46 x 10^3 J
b) 4.16 x 10^-3 Cal
c) 32.0 Cal
d) 2.35 x 10^5 J
Work Step by Step
1 cal = 4.184 joule and 1 joule = 0.239 cal.
a) 588 cal = 588 * 4.184 joule = 2.46 * 1000 J
b) 17.4 joule = 17.4 * 0.239 cal = 4.16 * 10^-3 cal
c) 134 kJ = 134 * 1000 J = 134 * 1000 * 0.239 cal = 32.0 * 10^3 cal
d) 56.2 cal = 56.2 * 4.184 joule = 235.14 joule
