Given,
Mass of sample = 22.3 g
Volume occupied = 31.24 mL
We know that
So,
According to the rule of division for significant figure, the answer should be reported based on the minimum number of significant figures in the given value. So, here minimum significant figure is three (22.3g). So,
Now, write in scientific notation as
Hence,
Answer: 7.14x10-1 g/mL
Let me know if you have any queries regarding this.

Question 3 5 pts Gold nanoparticles are typically prepared by the reduction of aurochloric acid (HAUCla) with boiling sodium citrate. The sodium citrate is used in excess and it is assumed that 100% of the Au atoms end up as part of the nanoparticles. If you start with a 1.00% (w/w) aqueous solution of HAC14:3H20 (aurochloric acid is typically available as the trihydrate) and the average particle diameter is 20.0 nm, what is the concentration of Au nanoparticles in the...
