Answer:True
Explanation:
If a substance is pure, it will have exactly the same density as that reported for that particular substance in standard literature or vary within very narrow limits. Hence we can determine the purity of a gold sample by measuring it's density.
Explanation:
2-methyl pentane
At first, we need to select a long chain.
Then, we should number that chain (Numbering will start from that side from which attachment is closer)
Then, For IUPAC name, at first we write the position at which substituent is attached then, name of subsitent and finally the chain name and suffix.
Here,
position of substituent = 2
name of substituent = -methyl
chain name = pent
suffix = -ane
Then,
IUPAC name is 2-methyl pentane
I would say a number about 545.
