How many grams of iron are in 350 mg of iron?-
Mamont248 [21]

Answer:

0.350 g of iron

Explanation:

Step 1: Given data

Mass of iron (m): 350 mg

Step 2: Convert the mass of iron to milligrams

In order to convert the mass of iron from grams to milligrams we need a conversion factor. In this case, the conversion factor is 1 g = 1,000 mg.

350 mg Fe × 1 g Fe/1,000 mg Fe = 0.350 g Fe

350 milligrams of iron is equal to 0.350 grams of iron. We conserve the 3 significante figures of the original data.

Explanation :

Isomer : It is defined as a molecule have the same molecular formula but the different chemical structure.

There are three structural isomers of n-hexene that is based on the location of the double-bonded carbon atoms with the other atoms.

In n-hexane, 'n' shows that the chain should be straight chain there is no branching.

The three structural isomers of n-hexene are:

(1) 1-hexene

(2) 2-hexene

(3) 3-hexene

Thus, the structural formulas for each of the possible isomers of n-hexene are shown below.
