Question

A solution is prepared by adding 5g of a substance x into the water.calculate the mass percent of the solute.​

Answer 1

Answer:-

• Mass of x =5g
• Mass of water=18g

We know that

$\boxed{\sf Mass\%\:of\:x=\dfrac{Mass\;of\:x}{Mass\:of\:Solution}\times 100}$

$\\ \sf\longmapsto Mass\%\:of\:x=\dfrac{5g}{5g+18g}\times 100$

$\\ \sf\longmapsto Mass\%\:of\:x=\dfrac{5g}{23g}\times 100$

$\\ \sf\longmapsto Mass\%\:of\:x=21.74\%$

$\\ \underline{\boxed{\bf{\therefore Mass\%\:of\:the\:x=21.74\%.}}}$
