Hurry will give brainliesthow much heat is needed to melt 45.00 g of ice at 0°c if the latent heat of fusion of water is 333.7 j/g? a. 288.7 jb. 378.7 jc. 14,220 jd. 15,020 j

d. 15,020 J

Explanation:

As we know that heat required to change the phase of of ice is given as

here we we know that

m = 45.00 gm

also we know that

Latent heat is L = 333.7 J/g

Now from above formula

so correct answer will be

d. 15,020 J

it is given that trillions of microbes make up to 1% to 3% of the body mass.

let's take average of this percentage: 2%

consider the average mass of the human body as 70 kg.

then, trillions of microbes would have mass  

therefore, 100 trillion micro-organisms would weigh:

this is an approximate value and could change depending on the mass of the human body and percentage of the microbes present in it.

average mass per microorganism =
