Question

There is 18g of glucose, 0.08 moles of glucose is taken out. Glucose left in the test tube is? Glucose ---> C6H12O6

Answer 1

3.6gm glucose left ,see solution for details

Answer 2

3.6 grams of glucose is left in the test tube.

Explanation:

According to avogadro's law, 1 mole of every substance weighs equal to molecular mass and contains avogadro's number $6.023\times 10^{23}$ of particles.

To calculate the number of moles, we use the equation:

$\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}$

given mass of glucose = 18 g

Molar mass of glucose $(C_6H_{12}O_6)$ = 180 g/mol

Putting in the values we get:

$\text{Number of moles}=\frac{18g}{180g/mol}=0.1moles$

Moles taken out = 0.08

Moles left = 0.1 - 0.08 = 0.02

Glucose left in the test tube is=$moles\times {\text {Molar mass}}=0.02mol\times 180g/mol=3.6g$
