Question

0.21 cal/g*C.

does the degree small zero go over the g or over the C

Answer 1

0.21cal/g[sup]o[/sup]C

do you mean this?

Answer 2

hm...

0.21cal/g^oC

Answer 3

No, the * symbol is the times sign and I used that as in 0.21 cal/g*C instead of just writing 0.21 cal/gC. It is read as "0.21 calories per gram per degree C" but most people say "0.21 calories per gram degree C." The degree sign is made by typing < followed by sup followed by the small letter o followed by >. Then you must turn off the superscript by < followed by / followed by sup followed by >. It works like this. 0.21 cal/g*^oC.

Answer 4

In practice on these boards we just omit the degree symbol.
