Answer:
184.46
Explanation:
(84.7°c x 9/5)+32=184.46 °F
mass of 1 mole of N is 14g
so mass of 3.45 mole is
3.45 × 14 = 48.3 g
Answer:
Explanation:
I think option d is correct
To solve this we use the
equation,
M1V1 = M2V2
where M1 is the concentration of the stock solution, V1 is the
volume of the stock solution, M2 is the concentration of the new solution and
V2 is its volume.
2.5 M x V1 = 1.0 M x .250 L
<span>V1 = 0.10 L or 100 mL of the 2.5 M HCl solution is needed
Hope this helps.</span>
