If the pressure of a gas is 2.43 atm what is it’s pressure in kpa

The pressure of the gas is 246 kPa.

p = 2.43 atm × (101.325 kPa/1 atm) = 246 kPa  

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
