Jawaban:

6.44L

Penjelasan:

To calculate the volume of a gas, you can use the ideal gas law:

PV = nRT

where:

P is the pressure of the gas, in atmospheres

V is the volume of the gas, in liters

n is the number of moles of the gas

R is the ideal gas constant, which is 8.31 J/mol*K

T is the temperature of the gas, in Kelvins

To use this equation, you first need to convert the temperature to Kelvins by adding 273.15 to the temperature in degrees Celsius. In this case, the temperature would be 275.27 K.

You can then plug the values into the equation:

V = (nRT) / P

= (1.90 mol * 8.31 J/mol*K * 275.27 K) / (6.00-10-1 atm)

= 6.44 L

So the volume of 1.90 mol of a gas at 2.12-102 °C and 6.00-10-1 atm is approximately 6.44 L.
