Question

calculate the mass of 10²³ molecules​

Answer 1

Answer:

Avogadro's number is a very important relationship to remember: 1 mole = 6.022×1023 6.022 × 10 23 atoms, molecules, protons, etc. To convert from moles to atoms, multiply the molar amount by Avogadro's number. To convert from atoms to moles, divide the atom amount by Avogadro's number (or multiply by its reciprocal).

Answer 2

Explanation:

ANSWER

1 mole of NH

3

has 6.023×10

23

molecules of NH

3

.

So, the mass of 6.023×10

23

molecules of NH

3

. is the mass of 1 mole of NH

3

i.e. molar mass of NH

3

.

Molar mass =14.01+3(1.01)
