How many grams of mgbr2 are needed to produce 75g or metal?

Answer : The mass of needed to produce are, 1150 grams

Solution : Given,

Mass of metal (magnesium) = 75 g

Molar mass of magnesium = 24 g/mole

Molar mass of = 184 g/mole

First we have to calculate the moles of metal (magnesium).

Now we have to calculate the moles of .

The balanced chemical reaction will be,

From the balanced reaction we conclude that

1 moles of magnesium react to give 1 mole of

6.25 moles of magnesium react to give 6.25 moles of

Now we have to calculate the mass of

Therefore, the mass of needed to produce are, 1150 grams
