<span>Tin has a molecular weight of 118.7 That is the mass in grams of one mole. 3.50
</span><span>118.7 = 415Four hundred and fifteen grams</span>
Explanation:
Specific heat capacity of gold (S)
= 0.126 J /kg°C
mass (m) = 350 g = 0.35 kg
difference in temperature (dt)
= 88.5°C - 24.6°C
= 63.9° C
Now
Energy released (Q)
= m*s*dt
= 0.35 * 0.126 * 63.9
= 2.81799 Joule
Hope it will help :)
The answer is Na < Cl
Chlorine is more electronegative than sodium because this follows the trend of the periodic table. The trend states that an element's electronegativity increases from left to right of a period and bottom to up of a group. Since sodium and chlorine are from the same period, and chlorine is at the right of sodium, chlorine is more electronegative.
Answer:
molecules present in, 76 gram of fluorine
Explanation:
atomic weight of fluorine is 19 g per mole, molecular weight is 38g per mole .
Therefore 76 gram fluorine contains 1976=4 gram atom
Both in the phase of a liquid & has similar qualities like both molecules.
