The radiosity of this surface is 299.95W/m².
<h3>
Calculation :</h3>
Given, € 0.8
Ta=0°C 273K
For opaque body., T = 0
a+ p = 1
€ = a (Kirchoff's Law)
p = (1-E)
Radiosity = leaving energy from the surface
= px 240 +€σT4
= (1-E) × 240 +0.8 x 5.67 x 10-8 (2734)
= (1-0.8) × 240 +0.8 x 5.67 × 10-8 (2734)
= 299.95W/m²
So, now after doing the calculations we can say that the radiosity of the surface was 299.95W/m².

Check table T and use the concentration equation. Molarity= moles of solute/ liters of solution.
So 0.240 = x/ 1.65 once u find the # of miles of solute (x=.396) and substitute that
Wait I'm not sure if it's correct
3 zots = 7 wots
3 zots × (3 dooms/2 zots) = ⁹/₂ dooms
⁹/₂ dooms × (7 farzes/4 dooms) = ⁶³/₈ farzes
⁶³/₈ farzes × (4 bings/9 farzes) = ⁷/₂ bings
⁷/₂ bings × (2 wots/1 bing) = 7 wots
Answer:
0.71
Explanation:
The molecular mass of NaCl is, 23+35.5
= 58.5
1 mole means molecular mass (in gram)
In 58.5 gm NaCl there is 1 mole.
So, 42.1 gm NaCl contains 42.1/58.5 =0.71 moles.
