Question

As an instructor is preparing for an experiment, he requires 225 g phosphoric acid. The only container readily available is a 150-mL Erlenmeyer flask. Is it large enough to contain the acid, whose density is

1.83g/mL?

225g:______mL
a) 112.30mL
b) 122.95mL
c) 123.00mL
d) 114.75mL

Answer 1

The volume of the phosphoric acid is 123.00 mL, which makes the 150-mL Erlenmeyer flask large enough to contain it.

Step-by-step explanation:

The volume of the acid can be calculated by dividing its mass by its density.

In this case, to find the volume of 225 g of phosphoric acid with a density of 1.83 g/mL:

Volume = Mass / Density

Volume = 225 g / 1.83 g/mL = 123.00 mL

Therefore, the answer is 123.00 mL (Option c).
