The density of helium is .178 kg/cu. m at STP. what is the density at 25 deg Celsius and 98kPa.
\n" ); document.write( "----------
\n" ); document.write( "Using 0C for standard temp and 100 kPa for standard pressure:
\n" ); document.write( "0C = 273.2K
\n" ); document.write( "25C = 298.2K
\n" ); document.write( "---
\n" ); document.write( "d = 0.178*(273.2/298.2)*(98/100)
\n" ); document.write( "= 0.1598 kg/cm
\n" ); document.write( "
\n" ); document.write( "
\n" );
