Answer:

pH = 1.771

Explanation:

given data

weight = 613 mg

volume of solution = 360 mL

solution

we get here first molarity that is

molarity = \frac{weight}{molecular \ weight} \times \frac{1000}{volume \ of\ solution}       .................1

put here value

molarity = \frac{613}{100.46} \times \frac{1000}{360}

molarity = 0.01694 M

and

pH = -log[0.01694]

pH = 1.771

Assume that you did the following dilutions
MrMuchimi
Below is the solution. I hope it helps. 

CfVf = CiVi 
<span>Cf = (CiVi)/ Vf </span>

<span>i. Cf = [ (10^-6 mol / L) (1 mL) (1L / 1000 mL) ] / [ (1kL) (1000L / 1 kL) ] = 1x10^-12 M → use as Ci in next dilution </span>
<span>ii. Cf = 1x10^-19 M → use as Ci in next dilution </span>
<span>iii. Cf = 1x10^-22 M </span>

1. Which type of heat transfer does a fan give off? Explain why you think that way.
Ksenya-84 [330]

Answer:

Convection is a heat transfer mechanism where heat moves from one place to another through fluid currents. Forced convection is simply using this mechanism in a useful way to heat or cool a home efficiently, such as using a fan.
