How many lone pairs does nh2 have
Web8 apr. 2024 · NH 4+ (ammonium) has one nitrogen atom and four hydrogen atoms. In the NH 4+ Lewis structure, there are four single bonds around the nitrogen atom, with four hydrogen atoms attached to it, and none of the atoms has a lone pair. Also, there is a positive (+1) charge on the nitrogen atom. Steps. #1 Draw a rough skeleton structure. Web5 uur geleden · And to get our final answer, we can now use the equation mass = relative formula mass x moles. 84 g mol^-1 x 0.03 mol = 2.52 g. So the final answer in this case should be 2.52 g. Ofc, not all 4 mark calculations will be exactly like this, but this example should teach you the following lessons:
