Question

Calculate the number of moles of Cu(C2H3O2)2 present in 200 gram

Answer 1

Answer:

1.101

Explanation:

moles= weight/ molar mass

molar mass of the given compound= 181.546

moles= 200/181.546= 1.101

Answer 2

Given:

200 grams of $Cu(C_2H_3O_2)_2$.

To find:

We have to find the number of moles.

Solution:

To determine the number of moles we have to follow the below steps as follows-

The given compound is $Cu(C_2H_3O_2)_2$.

The atomic weight of the Cu atom is 63 grams.

The atomic weight of the H atom is 1 and the C atom is 12 grams.

The atomic weight of an Oxygen atom is 16 grams.

Thus, the molecular weight of the compound is 63+(12×2+3×1+16×2)×2=181 grams.

Thus 181 grams of $Cu(C_2H_3O_2)_2$ occupy 1 mole.

So, 200 grams of $Cu(C_2H_3O_2)_2$ will occupy 200/181=1.1 moles.

So, 200 grams of $Cu(C_2H_3O_2)_2$ will occupy 1.1 moles.
