How do you calculate the number of moles in 4.637 grams in Mg?

For this you need the atomic mass of Mg. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel.4.637 grams Mg / (24.3 grams) = .191 moles Mg

What mass of magnesium will react with 497.1 mL of oxygen at 157.6C and 0.959 ATM?

The balanced chemical reaction equation is2 Mg + O2 ----> 2 MgOIdeal gas law gives oxygen moles :n = PV/RT = ( 0.959 atm ) ( 0.4971 L )/ ( 0.08205 L - atm/mol - K ) ( 157.6 + 273.2 K )n = 0.01349 mole O2Two moles og Mg are needed for each mole of O2.moles Mg needed = ( 2 ) ( 0.01349 ) = 0.02697 moles MgMass of Mg = ( mols of Mg ) ( M of Mg )Mass of Mg = ( 0.02697 mol ) ( 24.31 g Mg/mol Mg ) = 65.57 grams of magnesium

What is the mass of magnesium oxide when you burn 4 grams of magnesium?

Mg grams -> (use Mg's molar mass) -> Mg moles -> (use ratio of moles - use balanced equation) -> MgO moles -> (use MgO's molar mass) -> grams MgO set up the equation: Mg + O2 --> MgO (we know the product is MgO and not MgO2 because magnesium has a charge of 2+ while oxygen has a charge or 2-) balance the equation: 2Mg + O2 --> 2MgO Molar mass of Mg: 24.31 g/mol Molar mass of MgO: 44.30 g/mol (add the molar mass of Magnesium - 24.31g/mol and the molar mass of Oxygen - 15.99g/mol together) (use periodic table to find these) 7.0 grams of Mg To find the moles of Magnesium you use the molar mass of Mg. (7.0 g Mg)*(1 mol Mg / 24.31 g Mg) =0.2879 moles Mg notice how the grams cancel to leave you with moles - remember dividing by a fraction is the same as multiplying by the reciprocal Now use the balanced equation's coefficients and the moles of Mg to determine the number of moles of MgO present. 2Mg + O2 --> 2MgO 2 moles Mg : 2 moles MgO -> divide both sides by 2 and it obviously becomes a 'one to one' ratio. This means that the number of moles of Mg is equal to the number of moles of MgO. This means that there are 0.2879 moles of MgO. Now that we know MgO's molar mass and the number of moles of MgO we have, the grams of MgO produced can be determined. (0.2879 moles MgO)*(44.30 g MgO / 1 mol MgO) = 12.75 grams MgO
