Question

Calculate the amount of Cu(NO3)2 which is required to get 1.0 g of copper.

Answer 1

Explanation:

get CU and no3 taken twice which is required to get 1.0 proper remove the CU CU is the copper so see you remind the 1.0 grams of copper

Answer 2

Answer:

0.015

Explanation:

By reaction between Cu and NO₃

  Cu + 2NO₃ → Cu(NO₃)₂

From this we find that 1 mole of Cu produces 1 mole of Cu(NO₃)₂

No. of moles in 1g of Cu=   given mass/gram atomic mass

                                       =1/63.54

                                       =0.015

Since no. of moles of copper and copper nitrate are equal from above reaction, 0.015 moles of copper nitrate will be obtained from 1g of copper.
