What is the mass of 5.0 x 106 molecules of H2O?

Sagot :

Answer:

The mass of

5.00

×

10

23

molecules of

N

2

is

23.3 g N

2

.

Refer to the explanation for the process.

Explanation:

One mole of

N

2

contains

6.022

×

10

23

molecules. The mass of one mole of

N

2

is

28.014 g/mol

.

To determine the mol

N

2

molecules, divide the given number of molecules by

6.022

×

10

23

molecules/mol by multiplying by the inverse. Then multiply by the molar mass of

N

2

.
