V\3. The atomic masses of any two elements contain the same number of _a. atoms
b. grams
c. ions
d. milliliters

Answers

Answer 1

Answer:

a. atoms

Explanation:

Let's take as example carbon and lead. Carbon have an atomic mass of 12 a.m.u while lead have an atomic mass of 207 a.m.u. Value of atomic masses are the same with as the value of molar masses. So carbon have a molar mass of 12 g/mole while lead have a molar mass of 207 g/mol.

Avogadro's number it tell us that in 1 mole of particular substance there are 6.022 × 10²³ particles. Taking in account this, in 12 g of carbon there are 6.022 × 10²³ carbon atoms and in 207 g of lead there are 6.022 × 10²³ lead atoms atoms.

The atomic mass of any two elements contain the same number of atoms.

Convert 47.2 g CO= ______ molecules CO

Answers

Answer:

1.01 x 10^24 molecules

Explanation: This problem is solved by remembering Avogadro's number and since we have the mass of CO, we can easily calulate the number of moles.

Molecular Weight CO : 28.01 g/mol

47.2 g * 1mol / 28.01 g = 1.68 mol

Now 1 mol of CO is 6.022 x 10^23 molecules ( Avogadro's Number) then

1.68 mol CO * 6.022 x 10^23 = 1.01 x 10^24 molecules

How many molecules are in 2.00 moles of h2o

Answers

1 mole = 6.022×10^23 atoms. 1 water molecule = 2 Hydrogen atoms + 1 oxygen atom. So, 1 mole H2O = 1.2044×10^24 hydrogen atoms. Therefore 2 mole H2O will have 2.4088×10^24 hydrogen atoms.
