Question

calculate the concentration of a solution in volume percent which contains 10 gram of potassium nitrate dissolved in 150 gram of water

Answer 1

ʜᴇʟʟᴏ ᴍᴀᴛᴇ!

ᴄᴏɴᴇᴄᴇɴᴛʀᴀᴛɪᴏɴ = ᴍᴀss ᴏғ sᴏʟᴜᴛᴇ / ᴍᴀss ᴏғ sᴏʟᴜᴛɪᴏɴ × 100

ʜᴇʀᴇ, ᴍᴀss ᴏғ sᴏʟᴜᴛᴇ = 10ɢ
ᴍᴀss ᴏғ sᴏʟᴠᴇɴᴛ = 150ɢ + 10ɢ = 160ɢ

ᴄᴏɴᴄᴇɴᴛʀᴀᴛɪᴏɴ = 10 / 160 × 100
= 6.25%

ʜᴇɴᴄᴇ ᴄᴏɴᴄᴇɴᴛʀᴀᴛɪᴏɴ ɪs 6.25%

ʜᴏᴘᴇ ɪᴛ ʜᴇʟᴘs

Answer 2

Hello!!

Concentration of volume= Volume of solute ÷ Volume of solution^100

=10÷160*100

100÷16

=6.25%
