Someone, please help! 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?
Please solve and explain fully.

Answer:

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 $
