Answer:
Option A
Explanation:
Isomers usually have the same molecular formula but their structural formula are usually different.
In this question, the molecular formula is; C6H14.
Looking at the options, the only one that has the same molecular Formula and doesn't change branching far from what is given, the correct one is Option A.
Answer:
The temperature to the nearest 0.5°C is 98.5°C
Answer:
D. the mass of one mole of a substance
Explanation:
The molar mass of a substance is the mass in grams of one mole of the substance.
- For an element, the molar mass is the relative atoms mass expressed in grams.
- For example 23g of Na, 40g of oxygen
- For compounds, molar mass is the gram -formula or gram - molecular weight.
- This is determined by the addition of its component atomic masses and then expressed in grams.
The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles Lithium, or 6.941 grams.
