Question

How many joules are equivalent to 450 calories?

Answer 1

Below

Step-by-step explanation:

To convert calories to joules, you need to multiply the value by 4184

450 x 4184 = 1882800 J

If your teacher requires you to round to significant figures, you would round to 2 sig figs as 450 only has 2 sig figs

450 x 4184 = 1.9 x 10^6

Hope this helps! Best of luck <3
