1 mol of sodium = 23 grams (use the number on your periodic table).
0.7350 mol sodium = x

x = 16.905
You will get slightly less than this, depending on your periodic table. But the method will be the same.

Heptane has nine structural isomers are 2-methylhexane, 3-methylhexane, 2,2-dimethylpentane, 2,3-dimethylpentane, 2,4-dimethylpentane, 3,3-dimethylpentane, 3-ethylpentane and 2,2,3-trimethylbutane. Each compound must have the same molecular formula but the structure of each are different from each other.
Answer: 292.81
Get Kelvin by adding 273 to the Celsius You set it up with 7.82/355K • 6.45/X
Cross multiply 7.82•X and 6.45•355
You get 7.82X=2289.75
Divide both sides by 7.82 to get x=292.81
