If I have 6 moles of a gas at a pressure of 5.8 atm and a volume of 12 liters, what
is the temperature?

The temperature of the system is 141.36K.

According to the universal gas law, the pressure of a gas is directly proportional to the absolute temperature and number of moles of the gas and inversely proportional to the volume of the gas.

So in equation format,

=constant.

Or= R.

Here R is called the universal gas constant which has different values in different units.

Here the unit of volume is in litres and unit of pressure is in atmosphere.

So. Value of R comes as =0.082057.

So, according to the question,

P is 5.8atm, V is 12 litres and n is 6 moles.

So, = .

Or, T = .

Or, T = 141.36.

So,the temperature of the system is 141.36K

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
