Answer:
THE EMPIRICAL FORMULA OF THE SUBSTANCE IS C2H5NO
Explanation:
The steps involved in calculating the empirical formula of this substance in shown in the table below:
Element Carbon Hydrogen Nitrogen Oxygen
1. % Composition 40.66 8.53 23.72 27.09
2. Mole ratio =
%mass/ atomic mass 40.66/12 8.53/1 23.72/14 27.09/16
= 3.3883 8.53 1,6943 1.6931
3. Divide by smallest
value (0.6931) 3.3883/1.6931 8.53/1.6931 1.6943/1.6931 1.6931/1.6931
= 2.001 5.038 1.0007 1
4. Whole number ratio 2 5 1 1
The empirical formula = C2H5NO
population is the number of species living in a given area if this is regarding biology or earth studies :)
Answer:
Sa pagkain ng gulay ay maraming benepisyo sa kalusugan. Ang mga taong kumakain ng mas maraming gulay at prutas bilang bahagi ng overall healthy diet ay mas nababawasan ang panganib na magkaroon ng chronic diseases.

Ang gulay ay importanteng pinagkukuhanan ng nutrients gaya ng potassium, dietary fiber, folate (folic acid), vitamin A, at vitamin C.
Ang mga gulay ay mayaman sa potassium na nakatutulong na mapanatiling healthy ang daloy ng blood pressure.
Answer:
solid matter is composed of tightly packed particles. A solid when we retain its shape the particles are not free to move around. liquid matter is made of more Loosely packed particles. It will take the shape of its container. Particles can move about within a liquid, but they are packed densely enough that volume is maintained. gaseous matter is composed of particles packed so loosely that it is neither a defined shape nor a Define volume. A gas can be compressed
