How many grams of iron are in 350 mg of iron?-

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.

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current

what's the
