How many grams of magnesium are needed to react with 16g of 02?

Answer 1

I assume you mean this reaction.

2Mg + O2 --> 2MgO

16 or 160 ???

Either way the form is the same. We will use the 16 grams.

16 g O2 (1 mole O2/32 grams)(2 mole Mg/1 mole O2)

= 1.0 mole magnesium needed

======================

Answer 2

How many moles of magnesium are needed to react with 16 g of molecular oxygen?

Answer 3

so close to one that it doesn't matter about the variation.

Answer 4

0.50 moles O2 in 16 g (2 significants)

Answer 5

16g oxygen is 0.5mol, because oxygen is naturally O2 with a molar mass of 32g/mol. Total molecules is 0.5 x Avogardo, which is about 3x10^23 O2 molecules.

Answer 6

16g/32g=.5 mol

Answer 7

16 g oxygen is equal to 0,5 mole

Answer 8

0,5 moles

Answer 9

24

Answer 10

24 grams
