Question

How many moles of glucose is present in 20 grams

Answer 1

Answer:

O.111....

Explanation:

The mass of one mole (molecular mass) of glucose is

6 x (mass of carbon) + 12 x (mass of hydrogen) + 6 x (mass of oxygen)

That means -

6x12 + 12x1 + 6x16

The total answer is 180.

Number of moles of a compound = given mass / Molecular mass

That is equal to 20/180

So the answer is 0.1111.....

Answer 2

Answer:

Explanation:

The mass of one mole (molecular mass) of glucose is

6 x (mass of carbon) + 12 x (mass of hydrogen) + 6 x (mass of oxygen)
