Answer: 6
Explanation:
1) The structure shown is:
3CH₃CH₂O
2) The molecule is CH₃CH₂O. The chemical formula is CH₃CH₂O. The subscripts indicate the number of atoms of the corresponding atom in each molecule.
Then, there are 1 + 1 = 2 atoms of C, 3+ 2 = 5 atoms of H, and 1 atom of O.
3) The number in front of the molecule is the coefficient. It is 3, and it tells the number of molecules.
So, there are 3 molecules, which means that you have 3 times a many atoms as calculated previously.
That is 3×2 = 6 atoms of C, 3 × 5 = 15 atoms of H, and 3 × 1 = 3 atoms of O.
Then, the number of atoms of carbon (C) in 3 molecules is 6
Answer:
1)
(500.mL)(.200M)/.150M = 667 mL
667mL - 500mL = 167mL of water is needed
2)
1.0 L = 1000mL
M1 V1 = M2 V2
(1.6 mol/L) (175 mL) = (x)(1000mL)
x = .28M

Explanation:
Answer:
2cm^3
Explanation:
Use the density triangle: D=MxV
Switch for variables, V=M/D
Plug in numbers, 15.8g/7.9g/cm^3=2cm^3
