Calculate the number of millimoles contained in 500mg of feso4•c2h4(nh3)2so4.4h20 calculate the number of grams of bacro4 that would have to be dissolved and diluted to 100ml to prepare a 0.200m solution.

The mass of required = 5.0674 g

Explanation:

The formula for the calculation of moles is shown below:

Given :

Mass = 500 mg

Molar mass of = 382.1455 g/mol

Thus,

Also,

Molar mass of = 253.37 g/mol

Let the mass of the salt to prepare 100 mL 0.200 M solution = x g

The formula for the calculation of moles is shown below:

Thus,

Given that volume = 100 mL

Also,  

So, Volume = 100 / 1000 L = 0.1 L

Molarity = 0.200 M

Considering:

x = 5.0674 g

The mass of required = 5.0674 g

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
