The mass of the liquid is 280 g.
Mass = 200 mL × (1.4 g/1 mL) = 280 g
Iron rusts when exposed to air → chemical property
Your answer is going to be 200g
Answer:
58.316 is the formula weight of magnesium hydroxide
Answer:
Frequency = 1.25 ×10¹³ Hz
Explanation:
Given data:
Wavelength of light = 24.0 μm (2.4 ×10⁻⁵ m)
Frequency = ?
Solution:
Formula:
Speed of light = wavelength × frequency
Speed of light /wavelength = frequency
Frequency = 3×10⁸ m /s /2.4 ×10⁻⁵m
Frequency = 1.25 ×10¹³ s⁻¹
s⁻¹ = Hz
Frequency = 1.25 ×10¹³ Hz
