How many moles are in 8.2 x 10^22molecules of N2I6?

Chemistry
1 answer:
stiks02 [169]2 years ago
6 0

Answer:

First, find out how many moles of N2I6 you have. Then convert that to grams.

molar mass N2I6 = 789 g

moles N2I6 = 8.2x1022 molecules N2I6 x 1 mole/6.02x1023 molecules = 1.36x10-1 moles = 0.136 moles

grams N2I6 = 0.136 moles x 789 g/mole = 107 g = 110 g (to 2 significant figures)

How many kilojoules are released when 116 g of Cl2 reacts with silicon? Si(s)+2Cl2(g)→SiCl4(g)ΔH=−657kJ
alexandr402 [8]

Answer:-  537 kJ of heat is released.

Solution:- For the given equation, \Delta H is -657 kJ and the coefficient of Cl_2 in the balanced equation is 2. It means 657 kJ of heat is released when 2 moles of chlorine are used. We need to calculate the heat released when 116 g of Cl_2 are used.

Grams of chlorine are converted to moles and then multiplied by the \Delta H value and divided by the coefficient of chlorine and the set could be shown using dimensional analysis as:

116gCl_2(\frac{1mol}{70.9g})(\frac{657kJ}{2mol})

= 537.46 kJ

If we use the correct sig figs then it needs to be round off to three sig figs as the given grams of chlorine has only three sig figs. So, 537 kJ of heat is released.
