Question

How many litres of 25% (mass/ volume) copper sulphate solution would take to get 85g of copper sulphate?

i need answer asap
will mark u as brainliest if u answer

Answer 1

$\twoheadrightarrow\underline{\boxed{\pmb{\frak{\purple{ Solution: }}}}}\;\bigstar$

$\large{ \blue{\mathfrak{ \underline{\overline{\mid \:\: we\:know\:\: \mid}}}}}$

$M = V n$

$\large{ \red{\mathfrak{ \underline{\overline{\mid \:\: no\:of\:moles\:(n) \:\: \mid}}}}}$= $\large{ \pink{\mathfrak{ \underline{\overline{\mid \:\: mass\ \:\: \mid}}}}}$$\large{ \pink{\mathfrak{ \underline{\overline{\mid \:\: molar\:mass\:\: \mid}}}}}$
