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)

Answer ❤️
52% (m/v)
Volume of solution = Total mass of
Solution/ giving Density of solution
= 100/1.3
= 76.92L
Mass of volume = mass of H2so4/ Volume os solution × 100
= 40/76.92 × 100
= 52% (m/v)
hope help you
