Question

The number of carbon atoms in 45.21g C

Answer 1

Answer:

2.26 X10^24 carbon atoms

Explanation:

The number of carbon atoms in 45.21g C

carbon has an atomic mas of 12.01 gm

45.21 g  has 45.21/12.01 = 3.76 moles of C

a mole contains  Avogadros number of particles

6.022 X 10^23

3.76 moles contain 3.76 X6,022 X 10^23 =

2.26 X10^24 carbon atoms
