Answer:

50 ans..

Explanation:

Data :

v = ?

wavelength= 2.5 m

f = 20 Hz

Formula:

<em>s</em><em>p</em><em>e</em><em>e</em><em>d</em><em> </em><em>=</em><em> </em><em>(</em><em>f</em><em>r</em><em>e</em><em>q</em><em>u</em><em>e</em><em>n</em><em>c</em><em>y</em><em> </em><em>)</em><em>(</em><em>w</em><em>a</em><em>v</em><em>e</em><em>l</em><em>e</em><em>n</em><em>g</em><em>t</em><em>h</em><em>)</em><em> </em>

Solution:

v = ( 20 )( 2.5 )

v = 50 metre per second <em>A</em><em>n</em><em>s</em><em> </em><em>.</em><em>.</em><em>.</em><em>.</em><em>.</em><em>.</em><em>.</em><em>.</em><em>.</em><em>.</em><em>.</em>

A 2.5-L tank initially is empty, and we want to fill it with 10 g of ammonia. The ammonia comes from a line with saturated vapor
Alex17521 [72]

Answer:

592.92 x 10³ Pa

Explanation:

Mole of ammonia required = 10 g / 17 =0 .588 moles

We shall have to find pressure of .588 moles of ammonia at 30 degree having volume of 2.5 x 10⁻³ m³. We can calculate it as follows .

From the relation

PV = nRT

P x 2.5 x 10⁻³ =  .588 x 8.32 x ( 273 + 30 )

P = 592.92 x 10³ Pa
