The branched alkanes in boxes two and three all have molecular formula C6H14 and are isomers of the compound shown.
Isomers are compounds that has the same molecular formula but different structural formulas. Hence, isomers of compounds can be represented by the same molecular formula since they contain the same number of each atom.
The molecule shown has molecular formula C6H14. The branched alkanes in boxes two and three all have molecular formula C6H14 and are isomers of the compound shown.

Answer:
root-mean-sqaure = 2.77 m/s
average = 2.72 m/s
The root-mean-square is always the largest because it takes account of the variance of the spread of the data. The increase is related to the fact that the data varies to sample.
Explanation:
The rootmean-square (R) is the square root of the squares of the valeus divided by the number of the datas.
R = √(46.03)/6
R = 2.77 m/s
The average speed is the sum of the speeds divided by the number of datas:
A = 16.3/6
A = 2.72 m/s
Answer:-
95 grams
Explanation:-
Let the mass of water to be added be M
So total mass = 5 + M
So 5% of this solution has 5g of NaCl by mass.
∴ (M+5) x (5/100) = 5
M+5 = 5 x 100/5
M+5=100
M= 100-5
95
So amount of water to be added is 95 gram
