Question

** A) 540 cal **
B) 540 * 10^4 cal
C) 800 cal
D) 8000 cal

Is A correct? or cud it be B.?

Answer 1

You will need 540 calories per gram
water is 1 mL or 1 cm^3 per gram
so I get
540 * 100 csl
which is
5.40 * 10^4 cal
I hope B is a typo and should be 5.40*10^4

Answer 2

thnx again!
typo meaning?... the "cal" at the end?

Answer 3

you had typed 540*10^4
it should be
5.40 * 10^4

Answer 4

oops! ur right... typo there.
5.40*10^4
