ᴛʜᴇ ꜱᴜʙꜱᴛᴀɴᴄᴇ ʜᴀᴠɪɴɢ ᴀ ᴅᴇɴꜱɪᴛʏ ᴏꜰ 0.8ɢ/ᴄᴍ3 ʜᴀꜱ ᴀ ᴍᴀꜱꜱ ᴏꜰ 64 ɢʀᴀᴍ . ᴡʜᴀᴛ ɪꜱ ɪᴛ ᴠᴏʟᴜᴍᴇ ?

Answer 1

Explanation:

As density= mass/ volume

=) 8/10=64/x

=)x=80

Mass is 80 GM..

Answer 2

ɢɪᴠᴇɴ :-

• The density of a substance = 0.8g/cm³
• Mass of the substance = 64 grams

ᴛᴏ ꜰɪɴᴅ :-

• Volume of the substance

ꜱᴏʟᴜᴛɪᴏɴ :-

† Density = Mass / Volume

0.8 = 64/V

8/10 = 64/V

8 × V = 10 × 64

8V = 640

V = 640/8

V = 80 cm³

★ Hence, The volume of substance is 80 cm³
