Calculate the volume of 1 m hydrochloric acid (hcl) needed to prepare 10 ml of a 0.10 m hydrochloric acid solution.

V=1mL

Explanation:

[HCl]1=1M; V1=?

dilution formula:

V1*[ ]1=V2*[ ]2

⇒V1 = (V2*[ ]2)/[ ]1

⇒V1 = (10mL*0.1M)/(1M)

⇒V1 = 1mL

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).

the answer would be a
