What is the percentage concentration by mass of a solution that contains 0.098 kg of h2so4 in 500.0 g of h2o?

The percentage concentration by mass of a solution that contains 0.098 kg of in 500.0 g of is 16.4%

Explanation:

To calculate the mass percentage ,we use the formula:

Mass of = 0.098 kg= 98 g

Mass of water = 500 g

Putting values in above equation, we get:

Hence, percentage concentration by mass of a solution that contains 0.098 kg of in 500.0 g of is 16.4%

- 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
