The heat required to raise the temperature of a certain mass of sample to a specific temperature change, we use the formula mCpΔT where m is mass, Cp is the specific heat of the substance and ΔT is the temperature change. In this case, we substitute and form 1.25 g x 0.057 cal/g C *20 C equal to 1.425 calories.
It looks all correct to me, great job!
1 tablespoon = 0.5 ounces
We are required to find for 2 table spoons.
2 table spoons = 2 x 0.5 = 1 ounce.
Each bottle has 16 ounce.
Number of bottles = 4
So total number = 4 x 16 = 64 ounces.
Number of 2 table spoons = ![\frac{64 ounce}{1 ounce}](https://tex.z-dn.net/?f=%20%5Cfrac%7B64%20ounce%7D%7B1%20ounce%7D%20%20)
= 64
Thus there are 64 2-tablespoon doses are in 4 bottles of medication containing 16 ounces each.
