2.98 moles of H2 at 35°C and 2.3 atm are in a 32.8 L container. How many moles of H2 are in a 45.3 L container under the same co
zalisa [80]

Answer:

4.12 moles

Explanation:

We can solve this problem with the Ideal Gases Law.

P . V = n . R . T

In our first case we have:

P = 2.3 atm

V = 32.8 L

n = 2.98 moles

T → 35°C + 273 =  308K

Let's replace data for the second case:

2.3 atm . 45.3L = n . 0.082 . 308K

n = (2.3 atm . 45.3L) / (0.082 L.atm/mol.K . 308K)

n = 4.12 moles
