The integumentary system has multiple roles in homeostasis, including protection, temperature regulation, sensory reception, biochemical synthesis, and absorption. All body systems work in an interconnected manner to maintain the internal conditions essential to the function of the body.
Answer:
The weight percent of NaBr is 25,7%
Explanation:
Molality is a way to express the concentration of a chemical in terms of moles of substances per kg of solution. Weight percent is other way to express concentration in terms of mass of substance per mass of solution per 100
Thus, to obtain weight percent you must convert moles of NaBr to grams with molar mass and these grams to kilograms, thus:
2,50 mol / kg solution × (102,9 g / 1mol) × (1 kg / 1000 g) =
× 100 = 25,7 % (w/w)

An atom consists of three sub atomic particles which are protons, neutrons, and electrons. ... This nucleus is surrounded by the electrons as electrons revolve around the nucleus. Thus, we can conclude that out of the given options, a core of protons and neutrons surrounded by electrons best describes an atom.

The volume of the given solution is 2.5 L.
<u>Explanation:</u>
Volume of the solution = 2500 mL
We have to convert it into litres as,
1000 mL = 1 litre
To convert ml into litres we have to divide the millilitres by 1000, so that it can be converted into L.
Here given volume is 2500 mL.
Volume in L =
= 2.5 L
So the volume of the solution is 2.5 L.
