1 mol Au ---------------- 196.9665 g
0.150 mol Au ----------- ?
0.150 x 196.9665 / 1
= 29.54 g
hope this helps!
Answer: frequency =v/π= 3×10^8/6.9 ×10^-13=5×10^20
Explanation:) the relationship between the velocity and frequency of a wave is V=fπ ,where V=velocity of wave while the π or lander represents wavelength which was given in the question.f represents frequency of wave.velocity of waves differs,e.g sound waves has a velocity of 330m/s while electromagentic spectrum waves eg UV,infrared has a constant velocity called velocity of light =3×10^8.the question did not clarify the type of wave so I assumed it should be light. Which has a V= 3×10^8.so frequency was calculate d using velocity divided by wavelength (which. Was given).
Answer:
A
Explanation:
Converting thermal energy into electrical energy
Answer:
The molar mass of is 96.8 g/mol
Explanation:
The given molecular formula -
Individual molar masses of each element in the compound is as follows.
Molar mass of nitrogen - 14.01 g/mol
Molar mass of of hydrogen = 1.008g/mol
Molar mass of carbon = 12.01 g/mol
Molar mass of oxygen =16.00 g/mol
Molar mass of is
Therefore,The molar mass of is 96.8 g/mol
