Astudent takes a measured volume of 3.00 m hcl to prepare a 50.0 ml sample of 1.80 m hcl. what volume of 3.00 m hcl did the student use to make the sample? use mc020-1.jpg. 3.70 ml 16.7 ml 30.0 ml 83.3 ml

Use the dilution formula C1V1= C2V2

C1= 3.0 M
V1= ??
C2= 1.80 M
V2= 50.0mL

(3.0 M) x (V1)= (1.80 M) x (50.0 mL)

V1= 30.0 mL. 

The metal is named first

Answerit curves up and levels out.explanationwe assume that the container contains absolutely no ammonia to begin with as it states that "nitrogen gas and hydrogen gas" react to "produce ammonia."at dynamic equilibrium, the product and reactant concentrations are equal.this means that, starting from a concentration of zero, [nh₃] must curve "up" from zero and then level out to a constant concentration.
