Question

calculate the total number of atoms in 360g of glucose.

Answer 1

Answer:

glucose (C6H2206) molecular mass is 12×6+1×12+16×6=72+12+96=180g.

1 mole =6.022×10 to the power 23 (Na is avogadro no) 360=2mol then 180=Na then 360 =Na/180×360 atoms

Answer 2

Concept:

The relationship between the quantity of moles, weight, and molar mass of the chemical is provided by the mole concept. The atomic masses of the constituent elements that make up a molecule are added to determine the molar mass.

Given:

The mass of glucose = 360 g

Find:

Calculate the total number of atoms in 360 grams of glucose.

Solution:

A mole is a unit of measurement for high amounts of atoms and molecules in science. The amount of material that is present in a sample is how it is defined.

1 mole = 6.022×10²³ particles

This is also called Avogadro's number (NA) .

Molar mass is defined as the addition of atomic mass of atoms, combined in a molecule. Here, the molar mass of C6H12O6 is 180.01 g/mol.

The molar mass of glucose = 180.01 g/mol.

We use mole formula to calculate the no of moles present in glucose,

n = w/m

Where, n is the number of moles,

w is the weight of the compound and

m is the molar mass of the compound.

Now substituting the value in the given formula we get,

n = 360 g / 180.01 g/mol

n = 1.99 moles

The number of moles in 360g of glucose is 1.99moles.

Hence the total number of atoms in 360 grams of glucose is 1.99 moles.
