Δt = i Kf m
2.86 °C = (1) (1.86 °C kg mol-1) (x / 0.750 kg)
2.86 °C = (2.48 °C mol-1) (x)
x = 1.1532 mol
33.7 g / 1.1532 mol = 29.2 g/mol
Fusion or melting is the phase change from solid to liquid.
Answer:
Food or Sun
Explanation:
I'm not sure if it's food or sun, but try both
Answer:
0.4 * 10^-12 m
Explanation:
Frequency of the given Electromagnetic radiation is 7.50* 10^20 Hz
Speed of the electromagnetic radiation is 3*10^8 m/s
Hence wavelength is given by the formula: Speed/Frequency
Substituting the required values:
Wavelength = 3 * 10^8/7.50 * 10^20
=3/7.5 * 10^-12 = 0.4 * 10^-12 m
Hence the required wavelength of the electromagnetic radiation is 0.4*10^-12 m/s
