Question

The volume of 50g of a substance is 20 cm cube if the density of water is 1 gram centimetre ki power minus 3 will the substance float or sink

Answer 1

density= mass/ volume
➡ 50 /20=2.5g cm-3.
here the density of object is more than water . So it will sink

➧Mass = 50 g
➧Volume = 20 cm−³

➧ Density 0f Substance ➾ Mass 0f Substance / Volume 0f Substance

➾ 50 / 20
➾ 2.5 g cm−³ ...✔

Density 0f Substance is More, so 0bject will sink
