Question

Urgent. A density bottle weigh 0.25 when empty and 0. 75 when. Filled with water and 0.65N when filled with alcohol calculate the volume of water,the density of alcohol. Take density of water=1000kg/m3 acceleration due to gravity= 10m/s

Answer 1

ok, massbottle=m=.25N/9.8kg/N=250/9.8 grams

mass of water= 750/9.8 grams-massbottle
mass water=you do that math (500/9.8 grams)
volume bottle=masswater/density=
= 500/9.8*1g/cm^3=500/9.8 cm^3

alcohol:
massalcohol=650/9.8-250/9.8=400/9.8 grams
density alcohol=above mass/volume

Answer 2

I don't understand how you got the answer

Answer 3

Please explain it well for me to understand
