Question

A solution of H2SO4 is labeled 40%.the density of the Solution is 1.3gm/l . What is the concentration of the solution in % (m /v)

Answer 1

Volume of solution = Total mass of solution/Given density of solution

                                = 100/1.3

                                = 76.92 L

Mass by volume = mass of H2SO4/Volume of solution * 100

                             = 40/76.92 * 100

                             = 52%(m/V)


Hope this helps!

Answer 2

Answer:

52℅ (ᴍ/ᴠ)

Explanation:

ᴠᴏʟᴜᴍᴇ ᴏғ sᴏʟᴜᴛɪᴏɴ = ᴛᴏᴛᴀʟ ᴍᴀss ᴏғ sᴏʟᴜᴛɪᴏɴ/ɢɪᴠᴇɴ ᴅᴇɴᴄɪᴛʏ ᴏғ sᴏʟʟᴜᴛɪᴏɴ

= 100/1.3

=76.92ʟ

ᴍᴀss ᴏғ ᴠᴏʟᴜᴍᴇ=ᴍᴀss ᴏғ ʜ2sᴏ4 /ᴠᴏʟᴜᴍᴇ ᴏs sᴏʟᴜᴛɪᴏɴ ×100

=40/76.92×100

=52℅ (ᴍ/ᴠ)
