8 0

Answer:

C1V1=C2V2

C1 is 2.0mol/l

V1=?

C2=.4mol/L

V2=100ml or for this 0.1L

V1 is 20ml

Best way to prepare this is to measure out 20ml of the 2 molar solution and add 80mL to it to get to 100mL

Anyone can help me please

x=3

Use the pythagorean theorem:

a^2 + b^2 = c^2

4^2 + x^2 = 5^2

16 + x^2 = 25

x^2 = 25-16

x^2 = 9

√x^2 = √9

x = 3

If you have 730 moles of a gas at 304 Kelvin in a 4.50 Liter container what
vova2212 [387]

Answer:

4046atm

Explanation:

For this question you can use the ideal gas law,

<em />PV=nRT<em />

Where P is pressure, V is volume, n is moles of substance, R is the constant, and T is the temperature.

Because of the units given, R will equal .08026P=4046 atm

<h3>Rearrange the equation to solve for pressure:</h3>

P=\frac{nRT}{V}

Then, plug in the values (I'll be excluding units for simplicity, but they all cancel out for pressure in atm):

P=\frac{(730)(.08206)(304)}{4.5}

This will give you:

P=4046atm
