Chapter 3: Q3.2P (page 131)

(a) How many moles of Catoms are in 1 mol of sucrose(C12H22O11)?(b) How many Catoms are in 2 mol of sucrose?

Short Answer

Expert verified

(a) There are12 mol Catoms in 1 mol of sucrose.

(b) There are 1.45脳1023Catomsin 2 mol of sucrose.

Step by step solution

01

Calculating the moles of C atoms in 1 mole of sucrose

Since 12 moles of C atoms are present in 1 mole of sucrose.

Thus, the number of moles of Cis:

molesofC=1molofC12H22O11脳12molofCatoms1molofC12H22O11=12molofCatoms

02

Calculating the number of C atoms in 2 mole of sucrose

The number of moles can be converted into atoms by using Avogadro鈥檚 number. So, the number of atoms is calculated as:

numberofCatoms=(2molofC12H22O11)脳12molofCatoms1molofC12H22O11脳6.022脳1023Catoms1molofCatoms=1.45脳1023Catoms

The study of sulfur-nitrogen compounds is an active area of chemical research, made more so by the discovery in the early 1980s of one such compound that conducts electricity like a metal. The first sulfur-nitrogen compound was prepared in 1835 and serves today as a reactant for preparing many of the others. Mass spectrometry of the compound shows a molar mass of 184.27 g/mol, and analysis shows it to contain 2.288 g of S for every 1.000 g of N. What is its molecular formula?
