sugar C6H12O6 80 mg/dL to 120 mg/dL

sugar C6H12O6 80 mg/dL to 120 mg/dL

 

 

The concentration of sugar (glucose, C6H12O6) in human blood ranges from about 80 mg/dL before meals to 120 mg/dL after eating. The abbreviation dL stands for deciliter = 0.1 L. Find the molarity of glucose in blood before and after eating.

C6H12O6의 몰질량 = 180.16 g/mol

 

 

 

1) before eating

 

(80 mg/dL) (1 g / 1000 mg) (1 mol / 180.16 g) (1 dL / 0.1 L)

= (80) (1 / 1000) (1 / 180.16) (1 / 0.1)

= 0.00444 mol/L

= 4.44×10^(-3) M

 

 

 

2) after eating

 

(120) (1 / 1000) (1 / 180.16) (1 / 0.1)

= 0.00666 mol/L

= 6.66×10^(-3) M
