What would be the mass of 6.022 x 10^23 argon atoms?

39.948g Ar, or if you need to round it up then 39.95g

Explanation:

Conversion units: 1 mole is 6.022 x 10^23 molecules, that includes atoms too.

First Step: Convert atoms to moles:

6.022 x 10^23 Ar atoms × = 1 mole Ar

Second Step: Convert moles to grams

There is 39.948 grams in one mole of Argon so

1 mole Ar x 39.948g = 39.948g

- calcium has greater affinity to bond with electron receptors than hydrogen does and hence, it has the ability to replace hydrogen in most of its compounds.

- lithium has 2 valence electrons in the product because it can make only 1 bond with hydrogen. beryllium has 4 valence electrons in the product because it can only make 2 bonds. it has fewer electrons than neon and can react with electron donors. each hydrogen has 2 valence electrons, the same as helium.

- the covalent bond formed between carbon and hydrogen is polar because carbon is more electronegative than hydrogen and it attracts the bonded electron pair closer to itself, thus giving hydrogen a partial positive charge.

- a hydrogen bond is a relatively weak bond that hydrogen atoms make with the electronegative atoms nitrogen, oxygen or fluorine.

so the best choice is a.) 2 calcium (ca) atoms
