depend on which of them , they can have for example we have 1-buten ,2buten , iso buten(structural isomers) also they can have sterio isomers too
Answer:
33.8 g Solution
Explanation:
A chemistry student needs 15.0 g of methanol for an experiment. The concentration of ethanol in the solution is 44.4% w/w, that is, there are 44.4 g of methanol every 100 g of solution. The mass of solution that would contain 15.0 g of methanol is:
15.0 g Methanol × 100 g Solution/44.4 g Methanol = 33.8 g Solution
Since 33.8 g are required and 320. g are available, there is enough solution for the requirements.
Answer:
2.5×10^20atoms
Explanation:
number of moles= number of particles/Avogadro's constant
number of particles=Avogadro's constant × number of moles
number of particles=(6.02×10^23) × (4.1×10^-4)
number of particles=2.5×10^20
Explanation:
