The density of water is 1.0 g/cm3 will rubbing alcohol float with a density of 0.81 g/cm3

Hello! Being so that if the density of a substance or object is lower than that of water or a liquid, then Rubbing alcohol will float because it's density is lower than that of the water! Please mark me brainliest if you find suitable! Have a fantastic Day!! :)

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation
