All of the statements are true
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.

In the summer, in the southern hemisphere. when it is summer is the northern, it is winter in the southern. all year along, the most sun hits the equator, but when it is winter in the northern hemisphere (thats when Alaska goes dark because of no sun) there is summer in the southern Hemusphere such as continents like south america, india, africa, and places like that :)
Not sure as don't know ratios, I think it could be 45.93g but don't take my word for it, it could be wrong.
The equations you need are moles = concentration x volume
and mass = moles x formula mass
