Problem 52P

Perform each conversion.

(a) 45.6 J to calories

(b) 355 cal to joules

(c) 43.8 kJ to calories

(d) 215 cal to kilojoules

Step-by-Step Solution:
Step 1 of 3

Solution 52P

Here, we are going to convert the unit from Cal to joule or Joule to cal.

(a) 45.6 J to calories

We know,

1 Cal = 4.1868 Joule

Therefore, the conversion factor = 

Thus,

45.6 J x  =  10.89 cal

Therefore, 45.6 J = 10.89 cal

(b) 355 cal to joules

We know,

1 Cal = 4.1868 Joule

Therefore, the conversion factor =  

Thus,

355 cal x  = 1486.31 Joule

And, 1000 kJ = 1 J

Therefore,

355 cal = 1486.31 Joule = 1.486 kJ

(c) 43.8 kJ to calories

We know,

1 Cal = 4.1868 Joule

1000 J = 1 kJ

Therefore, the conversion factor = ,...
