Convert 4.86 x 104g of mg to moles.

Explanation:

Number of moles equal to the given mass divided by molar mass of the element or compound.

Mathematically,       No. of moles =

The given mass is g and molar mass is 24.30 g/mol.

Therefore, calculate the number of moles as follows.

          No. of moles =

                                =

                                = mol

                                = mol

or,                             = 2000 mol

Thus, we can conclude that   g of Mg has 2000 moles.

Answer : The moles of magnesium (Mg) is,

Solution : Given,

Mass of magnesium (Mg) =

Molar mass of magnesium (Mg) = 24.31 g/mole

Formula used :

Therefore, the moles of magnesium (Mg) is,

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
