What is the mass of 0.28 moles of iron

1 mole has mass = 56 g  

0.28 mol has mass = 56 x 0.28 = 15.68 g

Hope this helps!

Given data:

Number of moles of iron = 0.28 M

Mass of iron = ?

Solution:

Formula : Mass of iron = Number of moles of iron * Molecular mass of iron

Putting values in above formula:

                                 Mass of iron = 0.28 * 55.84 = 15.63

                                 Mass of iron = 15.63

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?

you did not give any options thus this is the best answer i can give to you with this little information you have given

> they are both natural and not man made

> they can be tracked and predicted by the right tools
