Question

STP তে 203mL গ্যাসের 27 ডিগ্রি সেলসিয়াস উষ্ণতায় এবং 600mm hg চাপে আয়তন কত​

Answer 1

Answer:

Here, P=1atm=1.013×105N/m2P=1atm=1.013×105N/m2

M=32g=32×10−3kgM=32g=32×10-3kg

V = molar volume at STP

=22.4litre=22.4×10−3m3=22.4litre=22.4×10-3m3

Crms=?Crms=?

Crms=3RTM−−−−−√=3PVM−−−−−√Crms=3RTM=3PVM

=3×1.013×105×22.4×10−332×10−3−−−−−−−−−−−−−−−−−−−−−−−−−√=3×1.013×105×22.4×10-332×10-3

=461.23m/s=461.23m/s.
