This is a two-step question. First, convert the mass of NO2 into the number of moles of NO2. Secondly, quantify the number of moles of NO2 in terms of the number of moles of NO2. The steps and answer are as follows
The answer has been provided to three significant figures to correspond with the number of sig figs given in the mass.
Answer:
Explanation:
Given that:
The heat of combustion of methylhydrazine =
It means that:
1 mole of methylhydrazine on combustion, releases of energy
Molar mass of methylhydrazine = 46.072 g/mol
Means that, 1 mole of methylhydrazine contains 46.072 g of methylhydrazine
Thus,
46.072 g of methylhydrazine on combustion, releases of energy
Also,
1 g of methylhydrazine on combustion, releases of energy
206.2 g of methylhydrazine on combustion, releases of energy
Heat released =
Answer:
THE FINAL TEMPREATURE OF IRON SWORD IS
1331°C
Answer:
The number of molecules in CH4, also known as methane, is merely 0.85 * 6.02210 * 10 ^ 23 (Avogadro's Number). This amounts to <em><u>approximately 5.1 * 10 ^ 23 molecules</u></em><u> with the correct number of significant figures</u>.
