Answer:
2 only is a pretty accurate answer the others dont make sense to me.
Explanation:
Answer:
0.00013
Explanation:
I'm pretty sure. I first subtracted 1.87 from 2. I got 0.13. The conversion from mL to L is 0.001. I multiplied 0.13 and 0.001 and got <u>0.00013 mL.</u>
Answer:
It's nitrogen
Explanation:
cuz it has valence 3 and a diatomic gas at room temperature
Answer:
132 amu
Explanation:
ammonium sulphate is ![(NH_4)_{2} SO_4](https://tex.z-dn.net/?f=%28NH_4%29_%7B2%7D%20SO_4)
to calculate molecular weight we need
atomic weight of the element of the compound
here ammonium sulphate is formed by two elements
2 nitrogen , 8 hydrogen , 1 sulphur amd 4 oxygen
atonomic number of nirogen is 14 , hydrogen is 1 , sulphur has 32 and oxygen has 16
so lets calculate molecular weight of ammonium sulphate
2*14 + 8*1 + 1*32 + 4*16
28 + 8 + 32 + 64
132 amu
