1. If you have 1.505 X 10^24 atoms of oxygen in glucose (C1,0), how many grams
of glucose do you have ?

Respuesta :

Answer:

[tex]75.04gC_6H_{12}O_6[/tex]

Explanation:

Hello!

In this case, since one mol of any atom is related via the Avogadro's number and each mol of glucose has 6 moles of atoms of oxygen, it is possible to obtain the moles of glucose as shown below:

[tex]1.505x10^{24}atomsO*\frac{1molO}{6.022x10^{23}atoms O}*\frac{1molC_6H_{12}O_6}{6molO}\\\\=0.4165 mol C_6H_{12}O_6[/tex]

Thus, since the molar mass of glucose is 180.15 g/mol, the mass turns out to be:

[tex]0.4165mol*\frac{180.15g}{1mol} \\\\=75.04gC_6H_{12}O_6[/tex]

Best regards!
