Seawater contains approximately 3.5% nacl by mass and has a density of 1.02g/ml. what volume of seawater conatains 1.0g of sodium

28 mL

Explanation:

We want to know what volume of seawater contains 1.0 g of sodium.

We know that the total amount of water mass always 3.5% corresponds to the mass of sodium.

So if the total mass of sodium is 1.0g this is equivalent to 3.5% of 100% of the mass

Calculate 100% of the mass with a simple rule of three

The total mass of seawater containing 1 g of sodium is 28.57 g

Now we calculate the volume that corresponds to this mass with the density

replace the values in the formula

- 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
