Question

Сколько чистого Cu в 1 гр CuSO4

Answer 1

W(массовая доля Cu в CuSO4)=M(Cu)/M(CuSO4)=64/160=0,4(40%)
m(Cu)=w(Cu)*m(CuSO4)=0,4*1=0,4 г

Answer 2

Calculating the Amount of Pure Cu in 1g of CuSO4

To calculate the amount of pure Cu in 1g of CuSO4, we can use the molar mass of CuSO4 and the stoichiometry of the reaction.

Step 1: Calculate the Molar Mass of CuSO4 The molar mass of CuSO4 (copper(II) sulfate) is calculated as follows: m(CuSO4) = m*(CuSO4) = 500*0,16 = 80 [[2 #]]

Step 2: Calculate the Amount of Cu in CuSO4 Using the molar mass of CuSO4, we can calculate the amount of Cu in 1g of CuSO4: (CuSO4) = m/M = 80/160 = 0.5 [[2 #]]

Therefore, there is 0.5g of pure Cu in 1g of CuSO4.

This calculation is based on the molar mass of CuSO4 and the stoichiometry of the reaction, as indicated in the provided search snippets.
