There are 4.2 moles of an unknown gas at a pressure of 5.5 atm that also have a volume of 12.0 L. What is the temperature of this gas?

191.4K

Explanation:

Using the ideal gas law equation as follows:

PV = nRT

Where;

P = pressure (atm)

V = volume (L)

n = number of moles (mol)

R = gas law constant (0.0821 Latm/molK)

T = temperature (K)

According to the information provided in this question:

n = 4.2moles

P = 5.5atm

V = 12.0 L

T = ?

Using PV = nRT

5.5 × 12 = 4.2 × 0.0821 × T

66 = 0.345 T

T = 66/0.345

T = 191.4K

zfoods? ok, pressure is used to keep the heat inside and to keep the food perfect.

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.
