Answer:

0.00013

Explanation:

I'm pretty sure. I first subtracted 1.87 from 2. I got 0.13. The conversion from mL to L is 0.001. I multiplied 0.13 and 0.001 and got <u>0.00013 mL.</u>

An unknown solid acid has a formula h2x. How could you determine the molar mass of the unknown acid for a titration with 0.455 m
Goshia [24]

Answer:

The answer is in the explanation.

Explanation:

A titration of H₂X with KOH produce:

H₂X + 2KOH → 2H₂O + K₂X

It is possible to obtain the moles of H₂X because the moles of KOH are the spent volume of the titration in liters × 0,455M. As for a complete titration of H₂X moles you need twice moles of KOH you know the moles of KOH obtained are half H₂X moles.

As you know the mass of the solid acid that you titrate and molar mass of acid is:

mass of acid / moles of acid. You can determine the molar mass of the unknown acid.

I hope it helps!

A sample of an ideal gas at 1.00 atm and a volume of 1.72 l was placed in a weighted balloon and dropped into the ocean. as the
kolbaska11 [484]
If we analyze the situation analytically, there are situations or states. Then, we are also given with 2 values of pressure and 1 value of volume. Lastly, temperature was set as constant. Thus, this means we use the Boyle's Law.

P₁V₁ = P₂V₂
Let's find V₂.
(1 atm)(1.72 L) = (35 atm)(V₂)
Solving for V₂,
<em>V₂ = 0.049 L</em>
