6.2 divided by the mass number of NO3 is 0.1 moles. Anytime your trying to find the moles of something you divide it by the mass number of your combined elements.
I think the answer is A sorry if it’s wrong
Atomic masses<span> :

N =14 a.m.u
H = 1 a.m.u
O =16 a.m.u
Therefore:
( NH₄)₂O = (14 * 2) + (1 * 4 *2) + (16* 1) => 52.0 g/mol
The mass of the object can also be determined if the density and volume of an object are known.
True
After the process of Ore processing, Enrichment, Fuel production and being passed through the reactor core the last remaining step is spent fuel disposal.
