Derive Equations 9.6a and 9.7a, which may be used to convert mass fraction to volume fraction, and vice versa.

last resort, use else statement. Cannot put anything after the “else” expression or it won’t read it only “if” and “end” are needed the “elseif” and and “else” are not NEEDED >> %Day 7 MATLAB examples >> a=10;b=15;c=20; >> x=a**> y=a>c||b> %one means yes, zero means no >> z=a>c&&b> %these are 3 logical operators >> v=x&y v = 1 >> %if x is true and y is true, you should get a true for v as well >> %string compare syntax is "strcmp('Yes','No') >> %ex. s1='upon';s2={'Once','Upon','A','Time'};tf=strcmp(s1,s2) >> s1='upon';s2={'Once','Upon','A','Time'};tf=strcmp(s1,s2) tf = 0 0 0 0 >> %It's comparing each thing and saying yes this is true (1)**
