Answer:
48.84mL
Explanation:
H2SO4 + 2KOH → K2SO4 + 2H2O
From the question:
nA = 1
nB = 2
From the question given we obtained the following information:
Ma = 0.43M
Va =?
Mb = 0.35M
Vb = 120mL
Using MaVa / MbVb = nA/nB, we can easily find the volume of the acid required. This is illustrated below:
MaVa / MbVb = nA/nB
0.43 x Va / 0.35 x 120 = 1/2
Cross multiply to express in linear form
2 x 0.43 x Va = 0.35 x 120
Divide both side by the (2 x 0.43)
Va = (0.35 x 120) /(2 x 0.43)
Va = 48.84mL
Therefore, the volume of H2SO4 required is 48.84mL
EGGBEATER KICK: <em>RESTING AND PASSING</em>
There are two phases:
a power stroke and a recovery stroke. The power stroke is the same as the underwater pull on the freestyle stroke and creates power.
Answer:
104.1 mL
Explanation:
c1V1 = c2V2
V1 = c2V2/c1 = (0.333 M×2500 mL)/8.00 M
V1 = 104.1 mL
