To solve this we use the
equation,
<span> M1V1 = M2V2</span>
<span> 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.</span>
<span>
</span>
<span>M1 = .80 g H2SO4 / g solution (1018 g solution / L solution ) (1 mol / 98.08) = 8.30 M</span>
<span>
</span>
<span>8.30 (V1) = (5.0 M) (1.5 L)</span>
<span>V1 = 0.9036 L or 903.6 mL of the stock needed</span>
Answer:
(a) 750
(b) 1875
(c) 4875 or as a fracion 7/20
Step-by-step explanation:
Answer:
0
Step-by-step explanation:
The total number of events is
45+37+52+94+72 = 300
P(purple) = purple/total
= 0/300
=0
