Mass percent of methanol :
% mass = mass methanol / mass total
% mass = 15.0 / 100.0 + 10.0 + 15.0
% mass = 15.0 / 125.0
% mass ( methanol ) = 0,12 x 100 = 12%
hope this helps!
Answer:
Ba has the largest atom size
Answer: -345.2 KJ
Explanation: As we know that ,dG=dH-TdS
T=25+273=298 K
dG= -356 x1000-298(-36)= -356000+10728
=-345272 j
= -345.2 KJ
