Relationship Between Grams and Atoms: Glucose

CHEM-NWPPOI

How many hydrogen atoms are in a sample of glucose, ${ C }_{ 6 }{ H }_{ 12 }{ O }_{ 6 }$ (MM = $180.12\ g/mol$) that contains $7.6540\times { 10 }^{ 2 }$ grams of carbon?

The molar masses of H and C are $1.008\ g/mol$ and $12.011\ g/mol$, respectively. Recall that $1\ mole = 6.022\times { 10 }^{ 23 }$.

A

$127.45$

B

$1.9188\times { 10 }^{ 25 }$

C

$1.919\times { 10 }^{ 25 }$

D

$7.6750\times { 10 }^{ 25 }$

E

$7.675\times { 10 }^{ 25 }$
