dlinn [17]3 years ago
3 0

Answer:

0.17M

Explanation:

5kg of water contains 5 liters as the density of water is 1000 kgm^{-3}

Therefore one liter of water contains 31/5=6.2g of HCl

Molality of the solution = 6.2/36.46 =0.17M

A gas has a pressure of 3 atm at 350°C. What will its pressure be at 250°C? The volume and amount of gas is constant. Hint: Conv
vichka [17]

<u>We are given:</u>

P1 = 3 atm                  T1 = 623 K <em>(350 + 273)</em>

P2 = x atm                 T2 = 523 K <em>(250 + 273)</em>

<em />

<u>Solving for x:</u>

From the idea gas equation:

PV = nRT

since number of moles (n) , Volume (V) and the Universal Gas constant(R) are constants;

P / T = k   (where k is a constant)

the value of  k will be the same for a gas with variable pressure and temperature and constant moles and volume

Hence, we can say that:

P1 / T1 = P2 / T2

3 / 623 = x / 523

x = 523 * 3 / 623

x = 2.5 atm (approx)

Therefore, the final pressure is 2.5 atm

Westkost [7]

Answer:

2.28 m

Explanation:

Use the relationship  

λ=vf

 

to solve for wavelength λ. Substituting the known quantities yields:

λ=vf

 

λ=2.99 x 108 m/s1.31 x 108 Hz

 

λ=2.28 m
