Answer:
802.69 g
Explanation:
The molar mass of Barium nitrite is 229.34 g/mol, so 3.5 moles of it will have a mass of ...
3.5 mol × 229.34 g/mol = 802.69 g
Answer:
f = 3 × 10⁶ Hz
Explanation:
Given data:
Wavelength of wave = 1.0 ×10² m
Frequency = ?
Solution:
Formula:
Speed of light = wavelength× frequency
Frequency = speed of light / wavelength
speed of light = 3× 10⁸ m/s
f = 3× 10⁸ m/s / 1.0 ×10² m
f = 3 × 10⁶ s⁻¹
s⁻¹ = Hz
f = 3 × 10⁶ Hz
