The question is incomplete. the complete question is:
A chemistry student needs 35.0 g of pentane for an experiment. By consulting the CRC Handbook of Chemistry and Physics, the student discovers that the density of pentane is . Calculate the volume of pentane the student should pour out.Round your answer to 3 significant digits.
Answer: The volume of pentane the student should pour out is 55.9 ml
Explanation:
Density is defined as the mass contained per unit volume.
To calculate volume of a substance, we use the equation:
We are given:
Density of pentane =
Mass of pentane = 35.0 g
Putting values in above equation, we get:
(Conversion factor: )
Hence, the volume of pentane is 55.9 ml
Answer: Radiation
Explanation:
Any time you can feel heat without touching it, you are experiencing radiation.
SiO2 is the chemical formula silicon and oxygen
27 it would be neutral if it had 24 electrons and 24 protons but because it is +3 that means it had 3 more protons than electrons so the answer would be 24+3
