A is your answer................???
Answer:
730×10 6 g
Explanation:
each one mole of NH4NO3 has 2 moles of nitrogen (2×14)
N NH4NO3
2×14 14+(4×1) +14+(3×16)
28 80
? 2.086 × 10 9
2.086× 10 9 ×28 ÷80 = 730 × 10 6 g of Nitrogen
<span>Radio waves are a type of electromagnetic radiation with wavelengths in the electromagnetic spectrum longer than infrared light. Radio waves have frequencies as high as 300 gigahertz (GHz) to as low as 30 hertz (Hz). ... Naturally occurring radio waves are emitted by lightning and astronomical objects.</span>
Silicon has 14 protons Potassium has 19 electrons The neutrons are equal to the mass number minus the atomic number. Or the big number minus the small number on the periodic table. hydrogen 1 does not have a neutron.
iron =56 -26 for 30 neutrons in the nucleus
Chlorine 17 protons and 17 electrons. 18 or 19 neutrons on average.
<span>175.5g
</span>Cl(35.5) x 3 = 106.5
Na(23) x 3 = 69
106.5 + 69 = 175.5g
or
0g because sodium and chlorine are not chemically bonded.
