The concentration of sugar (glucose, c6h12o6) in human blood ranges from about 80.0 mg/100. ml before meals to 120. mg/100. ml after eating. find the molarity of glucose in blood before and after eating.

The molarity of glucose in the blood before and after meal is 0.044 mol/L and 0.066 mol/L respectively.

Molarity:

It is the measure of the concentration in grams of solute in 1 letter of solvent.

Where,

M - molarity

w - given mass of solute

m - molar mass of solute,

v - volume

Put before meal values,

put the After meal values, we get

M = 0.066 mol/L

Therefore, the molarity of glucose in the blood before and after meal is 0.044 mol/L and 0.066 mol/L respectively.

Answers:

0.0044 mol·L⁻¹; 0.006 66 mol·L⁻¹

Step-by-step explanation:

(1) Before eating

    80. mg/100. mL                 Convert milligrams to grams

=   80. mg/100. mL × 1 g/1000 mg  

= 0.080 g/100. mL                 Convert grams to moles

= 0.080 g/100. mL × 1 mol/180.16 g

= 4.44 × 10⁻⁴ mol/100. mL     Convert millilitres to litres

= 4.44 × 10⁻⁴ mol/100. mL × 1000 mL/1 L

= 0.0044 mol·L⁻¹

(2) After eating

     120. mg/100. mL                  Convert milligrams to grams

=   120. mg/100. mL × 1 g/1000 mg  

= 0.120 g/100. mL                   Convert grams to moles

= 0.120 g/100. mL × 1 mol/180.16 g

= 6.661 × 10⁻⁴ mol/100. mL     Convert millilitres to litres

= 6.661 × 10⁻⁴ mol/100. mL × 1000 mL/1 L

= 0.006 66 mol·L⁻¹

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
