Question

- I really need an answer pls -
How many grams of Cu(NO3)2 can be made from 2 moles of NaNO3 ?​

Answer 1

`\sf \underline{CuCl_2 +\pink{2NaNO_3} \longrightarrow \pink{ Cu(NO3)_2}+2NaCl}`

According to the equation, 1 mole of
`\sf CuCl_2` reacts with 2 moles of
`\sf NaNO_3` to produce 1 mole of
`\sf Cu(NO_3)_2` and 2 moles of
`\sf NaCl`

Molar mass of
`\sf Cu(NO_3)_2` -

`\:\:\:\:\:\:\longrightarrow \sf 63.5 + 2* 14 + 16 * 6 \\`

`\:\:\:\:\:\:\longrightarrow \sf 187.5 \\`

• Therefore, 1 mole or, 187.5 grams
  `\sf Cu(NO_3)_2` 2 can be made from 2 moles of
  `\sf NaNO_3`
