First of all, the unit of density is gm/l not l/gm (mass/volume). We must use ideal gas equation. PV= nRT, so that n/v = P/RT. Multiplying the left hand side by molar mass M is the density in gm/l. So that, (n/v)xM= (P/RT)xM = density(d). So M = dRT/P. So the temperature and pressure must be provided...

Density depends on both pressure and temperature. Hence without mentioning pressure and temperature we can't solve. Required formula: Density= (pressure ×molar mass)/(universal gas constant ×temperutre ink). On doing this problem be careful of unit.

is the question correct? density=g/l and not l/g. let's take d=3 g/l T=25 deg C (298K) using standard if not given P= 1 bar R= 0.08314 l.bar/K.mol According to the Ideal gas law: PV=nRT thus, P/RT=n/V now, n=no. of moles= wt. of compound(gas in this case)/molar mass of compound hence,...

molar mass= 2×vapour density = 2×3 =6

density = mass / volume so its unit can be gm / l not l / gm. first write accurate problem then ask

density is gm/cc. So, data is wrong

First you should correct the unit of density then apply PM=dRT and find ur ans

Something doesn't look correct in the question as unit of density is not l/gm, Since d=mass/volume, so numerator must have a unit of mass and same for denominator.

Can a fridge, left open in a closed room, be used to cool the room?
No. We should not do that. If we left the fridge door open, it will cool the room a little but also heat it up a lot more.

NREGA is mostly handled by women in rural areas. Why NREGA is mostly occurred in rural areas rather than urban areas?
It is because people in urban areas have sufficient scope to work and get paid while in rural areas (i.e. undeveloped) the scope of earning daily bread and butter is very less.
