As an instructor is preparing for an experiment, he requires 168 g glycerin. The only container readily available is a 150 mL Erlenmeyer flask. Is it large enough to contain the glycerin, whose density is 1.26 g/mL

Yes

Explanation:

m = Mass of glycerin = 168 g

Volume of glycerin that can fit in the container = 150 mL

= Density of glycerin = 1.26 g/mL

Volume the given mass of glycerin will occupy is

A mass of 168 g of glycerin will have a volume of 133.33 mL which is less than the 150 mL flask. So, yes the flask is large enough to fit 168 g of glycerin.

what is the question here. i think you messed up.

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8
