Pleasee help me I really need an answer help compare the mass of the starting substances to the new substances

copper(II) sulphate and sodium hydroxide starting mass 180g new mass 180g help with this

This is hard for me also but I am trying to find out answer

Explanation:

Please mark me as brainlist.

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm
