Answer:

Yes , 5 mole of Iron Oxide has mass of  798.5 g

Explanation:

Formula of iron oxide:

Fe_{2}O_{3}

Atomic mass of Fe = 55.84 amu

Atomic mass of O = 15.99 amu

Molar mass of Fe2O3 = 2(atomic mass of Fe) + 3(atomic mass of O)

= 2(55.84) + 3(15.99)

=111.68 + 47.97

= 159.69 g/mol

<u>Molar mass</u> always equal to <u>1 mole</u> of the substance.

1 mole = 159.69 g

5 mole =

=5\times159.69

= 798.45 g

199.5 grams unrefined dark crystalline sugar to cups
Dmitry [639]

Answer:

0.9975 cup  

Step-by-step explanation:

"Unrefined dark crystalline sugar" is what non-chemists call "brown sugar."

200.0 g brown sugar = 1 cup

 199.5 g brown sugar = 199.5× 1/200 .0

 199.5 g brown sugar = 0.9975 cup

A standard measuring cup is not capable of this precision and, furthermore, the mass of brown sugar you can get into a cup depends on how tightly you pack it.

Your Mole Day cake will be fine if you use 1 cup of brown sugar as usual.
