Question

A chemist prepares a solution of calcium sulfate (CaSO4) by measuring out 0.232 g of calcium sulfate into a 300.mL volumetric flask and filling the flask to the mark with water. Calculate the concentration in mol/L of the chemist's calcium sulfate solution. Be sure your answer has the correct number of significant digits.

Answer 1

5.6667*10^-3mol\L

Step-by-step explanation:

get the number of moles:

0.0232\(40+32+16+16+16+16)=1.7*10^-3

get the consentration:

1.7*10^-3 \0.3=5.6667*10^-3mol\L
