Question

The density of an ideal gas can be expressed as d = ____________.

विकल्प

• `"RT"/"PM"`

• `"RP"/"TM"`

• `"RM"/"TP"`

• `"PM"/"RT"`

Answer 1

The density of an ideal gas can be expressed as d = `underline("PM"/"RT")`.

Explanation:

PV = nRT

∴ PV = `"m"/"M" "RT"`

∴ P = `"m"/"V"."RT"/"M"`

∴ `"m"/"V" = "PM"/"RT"`

∴ d = `"PM"/"RT"` ........(∵ d = m/V)
