It's actually made or gas and dust that can extend hundreds of millions of kilometers away from the coma. most comets actually have two tails a plasma tell made of ionized gas and a dust tail made of small solid particles.
I would start by converting g/mL to g/L
75.00g/1000.0mL = 75.00g/L
Stoichiometrically, flip 75 onto the bottom so that grams cancel out and we are left with the number of L required.
(L/75.00g)(15g) -> this is essentially dividing 15g by 75g, which cancels the unit g, leaving us with 0.2L. If the question requires an answer in mL, just multiple the number of L by 1000.
The patient requires 200mL of glucose solution to receive his 15g of glucose.
It would be most likely to be found in carbohydrates
