Answer:
12 cm³
Explanation:
Always round to the place of the number with the least amount of significant figures.
1.74 and 3.09 have three significant figures. 2.3 has two significant figures. Therefore, the answer will be rounded to two significant figures.
1.74 cm × 2.3 cm × 3.09 cm = 12.36618 -> 12 cm³
(The 3 in the tenths place is less than 5 so drop it and all the numbers to the right of it.)

Answer:
hexane
Explanation:
This is a 6- carbon hydrocarbon with no multiple bonds or any functional groups (such as -OH). Thus, the prefix 'hex' refers to the 6 carbons and 'ane' refers to the molecule being an alkane.
Naming molecules:
<u>Number of </u><u>carbons</u>
• pentane: 5 carbons
• hexane: 6 carbons
• heptane: 7 carbons
• octane: 8 carbons
• nonane: 9 carbons
<u>Functional </u><u>groups</u> (for 6- carbons molecules)
• Alkene (C=C): hexene
• Alcohol (-OH): hexanol
• Alkyne (C≡C): hexyne
