Question

A solution is formed by adding 35 g of ammonium nitrate to 250 g of water. what is the percent by mass of ammonium nitrate?​

Answer 1

• Mass of solute=35g
• Mass of solvent=250g

$\\ \sf\longmapsto Mass\%=\dfrac{Mass\;of\:solute}{Mass\:of\:solvent}\times 100$

$\\ \sf\longmapsto Mass\%=\dfrac{35}{250}\times 100$

$\\ \sf\longmapsto Mass\%=\dfrac{7}{50}\times 100$

$\\ \sf\longmapsto Mass\%=7(2)=14\%$
