True or false? To prepare 20.0 mL of 2.00 M solution of hydrochloric acid from a 10.0 M stock solution, you should take 4.00 mL of the stock solution and add 20.0 mL of water.

Answers

Sorry I don’t know but o have to answer for pionts

False. To prepare 20.0 mL of 2.00 M solution of hydrochloric acid from 10.0 M stock solution, 4.0 mL of the stock solution and 16.0 mL of water would be needed.  

Recall the law of diffusion that:

C1V1 = C2V2, where C1 = initial concentration, V1 = initial volume, C2 = final concentration, and V2 = final volume.

In this case, if C1 =10.0 M, V1 = ?, C2 = 2.00 M and V2 = 20.0 mL

V1 = 2 x 20/10

         = 4.0 mL

Hence, 4.0 mL of the stock solution would be taken. Since the final volume is 20.0 mL, only 16.0 mL of water would need to be added and not 20.0 mL.

What is the number of particles in 15.0 g of H2O?

Answers

Answer:

We know that 18 g of H2O contains 1 mole (or 6.022 x 10^23) molecules of water because the molar mass of H2O is 18 g/mol.

So 1 g water will contain 1/18 moles of H2O molecules.

Now 15 g of water will contain 15/18 moles of H2O.

So molecules of H2O = (15/18) x 6.022 x 10^23 = 5 x 10^23 molecules.

Specific Heat Formula: q = mcΔT

q is heat (in Joules)m is mass (in grams)c is specific heat (in J/g °C)ΔT is change in temperatureExplanation:

Step 1: Define

[Given] m = 38.8 g

[Given] q = 181 J

[Given] ΔT = 36.0 °C - 25.0 °C = 11.0 °C

[Solve] c

Step 2: Solve for Specific Heat

Substitute in variables [Specific Heat Formula]:                                             181 J = (38.8 g)c(11.0 °C)Multiply:                                                                                                             181 J = (426.8 g °C)c[Division Property of Equality] Isolate c:                                                         0.424086 J/g °C = cRewrite:                                                                                                             c = 0.424086 J/g °C

Answers

Answer:

480 mL

Explanation:

15L  of  0.38M of NH3(aq.) means that we require 15x0.38 moles of NH3.

this is to be provided by 15M x V.  

Where V is volume in Liters.
