Question

Рассчитать массу сульфата меди(||), который можно получить из медного купороса массой 500г

Answer 1

1По формуле медного купороса СuSO4*5H2O подсчитай молекулярную массу 
Мr = (64+32+16*4)+5(1*2+16)=160+5*18=250 
2. в 250 г cuso4*5H2o-------160 г cuso4 
в 500 г ------------------------х г 

х=500*160/250=320 (г)CuSO4

Answer 2

Calculating the Mass of Copper Sulfate (CuSO4)

To calculate the mass of copper sulfate (CuSO4) that can be obtained from 500g of copper(II) sulfate pentahydrate (CuSO4·5H2O), we can use the following steps:

1. Determine the molar mass of CuSO4·5H2O: - The molar mass of CuSO4·5H2O is the sum of the molar masses of its constituent elements. - The molar mass of copper (Cu) is approximately 63.55 g/mol, sulfur (S) is approximately 32.07 g/mol, oxygen (O) is approximately 16.00 g/mol, and hydrogen (H) is approximately 1.01 g/mol.

2. Calculate the molar mass of CuSO4·5H2O: - The molar mass of CuSO4·5H2O can be calculated using the atomic masses of its constituent elements and considering the stoichiometry of the compound.

3. Determine the molar ratio of CuSO4 to CuSO4·5H2O: - The molar ratio of CuSO4 to CuSO4·5H2O can be determined from the chemical formula of the compounds.

4. Calculate the mass of CuSO4 that can be obtained: - Using the molar ratio and the given mass of CuSO4·5H2O, the mass of CuSO4 that can be obtained can be calculated.

Let's proceed with the calculations.
