The mass of one mole of any substance:

a. is equal to 6.02 x 1023 g
b. is equal to the sum of the atomic masses of every atom in the formula
c. is the same for all elements but not molecules
d. is the same for all elements and molecules

Answer : The correct option is, (B) is equal to the sum of the atomic masses of every atom in the formula.

Explanation :

As we know that, 1 mole of substance always contains number of atoms.

And the mass of one mole of any substance is different for all the elements and the molecules.

The mass of one moles of any substance is equal to the atomic mass unit. Or, we can say that it is equal to the sum of the atomic masses of every atoms in the given formula.

For example : The mass of one moles of water is, 18 gram/mole.

As the atomic mass of hydrogen and oxygen are, 1 g/mole and 16 g/mole. So, the mass of one moles of water is, 2(1 g/mole) + 16 g/mole = 18 g/mole.

Hence, the correct option is, (B) is equal to the sum of the atomic masses of every atom in the formula.

the dependant variable is spilled water

the independent is the heat

have a great day because if you dont you and i will be sad
