a solution has a density of 1.35g/cm3 calculate the mass in grams of this solution if it has a volume of 24.5L

33,075g

Explanation:

since density=mass/volume

1.35=x/24500(in cm3)

x=1.35*24500

=33075g

Given : a solution has a density of 1.35g/cm³ calculate the mass in grams of this solution if it has a volume of 24.5L

Solution : As we know that density is mass/vol. Therefore putting the value of density and volume we can get the mass.

Density = Mass/Volume

Mass = Density × Volume

Mass = 13.5g/cm³ × 24.5L

Now, as we know that 1L = 1000 cm³. So putting it in the volume we can get the final answer

Mass = 13.5 × 24.5(1000)

Mass = 13.5 × 24500

Mass = 330,750 g

- 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
