Someone, ! first, correct answer gets brainliest.
a chemist needs 2.00 g of a liquid compound.
a. what volume of the compound is necessary if the density of the liquid is 0.718 g/ml?
b. if the compound costs $2.41 per ml, what is the cost of 2.00 g?
solve and explain fully.

Explanation:

a)

You can calculate the volume of the compound using the following formula:

Density = Mass/Volume

0.718 = 2.00/Volume

Volume = 2.00/0.718 = 2.78 mL

b)

If 2.78 mL is equal to 2.00 g (according to letter a) and the price of the compound is $2.41 per mL , we can calculate like this:

1 mL 2.41 $

2.78 mL X

X = 2.78 x 2.41 = 6.70 $

b..

is the correct one

explanation:

covalent bonds form as valence electrons are shared between two atoms. lewis structures and structural formulas are common ways of showing the covalent bonding in organic molecules. formal charge describes the changes in the number of valence electrons as an atom becomes bonded into a molecule.
