Answer:

6813.7g

Explanation:

Calculate the mass

Let x be the mass

If 1 mol of Fe has a mass of 55.85 g

1 mol =55.85g

122mol= x

we have x= 122•55.85g=6813.7g

What are the benefits of scientists using the metric system worldwide?select all that apply
denis-greek [22]

There are several scales to determine the weight of material. The chose of the weight scale depends upon the size of the material. Like if we have to measure the molecular or atomic weight of  a molecule or atom we use gm. Like that for the bigger molecules like proteins the weight of the molecule is expressed by different scale due to its big size. Like that for big material like iron rods etc we generally use kilograms or ton. There are two types of measuring units one is C.G.S. and another is S.I. The S.I. units are more acceptable worldwide than that the C.G.S. units as the digit comes in SI units are easily handable than that of CGS.

Thus metric is used to determine a large weight of compounds which is a SI unit and handable.

2.3 moles of CaBr2 contains how many molecules
kkurt [141]

Avogadro's law states that in every mole of a substance, there are 6.022 \times 10^{23} molecules.

This means that in 2.3 moles, there are 2.3(6.022 \times 10^{23})=\boxed{1.4 \times 10^{24} \text{ (to 2 sf)}}
