Give the structure that corresponds to the following molecular formula and NMR spectra: C6H14O ¹H NMR: δ 0.91 (6H, d, J = 7 Hz); δ 1.17 (6H, s); δ 1.48 (1H, s; disappears after D2O shake); δ 1.65 (1H, septet, J = 7 Hz). ¹³C NMR: δ 17.6, δ 26.5, δ 38.7, δ 73.2.

There are 6.022 x 10^23 atoms of hg in 1 mole of hg. the number of atoms in 4.5 moles of hg can be found by multiplying 4.5 by 6.022 x 10^23 a. 2.7 x 10^24 b. 27 x 10^23 c. 2.71 x10^24 d. 27.099 x 10^23

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.
