n=20 mol
(NH)4 SO4
Atomic masses :
N- 14
H- 1
S- 32
O- 16
Therefore M= 14×2 + 1×8 + 32 + 16×4
= 132
m= nM
= 20×132
= 2640g
Answer:
10nm
Explanation:
Ultraviolet (UV) is a form of electromagnetic radiation with wavelength from 10 nm (with a corresponding frequency of approximately 30 PHz) to 400 nm (750 THz), shorter than that of visible light but longer than X-rays.
Answer:
The boiling point of water, or any liquid, varies according to the surrounding atmospheric pressure. ... With that much less pressure, you don't need to apply as much heat to push vapor pressure beyond the surrounding atmospheric pressure – in other words, water boils at a lower temperature.
Answer:
0.0125 moles of HCl
Explanation:
The equations for molarity is M=mols/L. If you divide 125mL by 1000 you will get 0.125L of HCl. You then multiply the 0.125L by 0.1M HCl. Then you will get you answer in moles of HCl which is 0.0125moles of HCl.
