You have 960 J in that many calories.

To go from calories to Joules, or vice versa, use the fact that 1 calorie is equivalent to 4.184 J. Use a simple conversion factor to get the value you need

#230cancel("cal") * "4.184 J"/(1cancel("cal")) = "962.32 J"#

Rounded to two sig figs, the number of sig figs in 230, the answer will be

#color(green)("960 J")#
