The temperature of a sample of gas at 80 kPa was quadrupled at constant volume. Calculate the final pressure

Provide the choices you are given. i would be happy to : ) you!

Electron equations of the given changes are as follow,a)                              cu      →      cu⁺²  + 2e⁻b)                              mg⁺²  +  2 e⁻      →      mgc)                              cl⁻    →      cl  +  1e⁻d)                              s  +  2 e⁻    →      s²⁻e)                                o²⁻      →      o  +  2 e⁻f)                              p  +  3 e⁻    →      p³⁻g)                              fe²⁺    →      fe³⁺  + 1 e⁻h)                              s²⁻    →      s⁴⁺  +  6 e⁻

Mars contains iron oxide in its crust

Ican't see the chart but the density of both nickel and cobalt is 8.90 g/cm3, so it would be one of those.
