Answer:

0.654 moles of gas

Explanation:

GIVEN DATA:

Here Volume =10.0 litre=10 dm3

Pressure=203kPa

Temperature:373k

R= gas constant=8.31 L -kPa/ mol-K.

REQUIRED DATA:

n=moles of gas sample

CALCULATION:

FROM GENERAL GAS EQUATION

PV=nRT

n=PV/RT

PUTTING THE VALUE WE GET

n=(203*10)/(8.31*373)

n=0.654 moles

Calculate the number of moles of ethanol acid in 30 cm³of 1 mol dm-³ solution ​
muminat

Answer:

May I assume "ethanol acid is just ethanol (it has one slightly acidic H atom).  If so, the molar mass is 46.02 g/mole.

Explanation:

We have 30 cm^3 [30 ml] of 1.0 M (1 mole/liter)  [1 dm³ = 1 liter].

That is 1 mole/liter.  30 ml would contain (0.030 liter)*(1 mole/1 liter) = 0.03 moles.

DaniilM [7]

Answer:

625 mL

Explanation:

From the question given above, the following data were obtained:

Volume of stock solution (V₁) = 250 mL

Molarity of stock solution (M₁) = 5 M

Molarity of diluted solution (M₂) = 2 M

Volume of diluted solution (V₂) =?

The volume of the diluted solution can be obtained by using the dilution formula as illustrated below:

M₁V₁ = M₂V₂

5 × 250 = 2 × V₂

1250 = 2 × V₂

Divide both side by 2

V₂ = 1250 / 2

V₂ = 625 mL

Therefore, the volume of the diluted solution is 625 mL.
