A prism can break white light up into the visible light spectrum. Visible light is a form of electromagnetic (EM) radiation, as are radio waves, infrared radiation, ultraviolet radiation, X-rays and microwaves. ... EM radiation is transmitted in waves or particles at different wavelengths and frequencies
Answer:
9.52 kg/mL
Explanation:
Density = mass/ Volume
= 100 kg/ 10.5 mL
= 9.523809524 kg/mL
OR
100 kg = 100 × 10^3 g
》Density = 100 × 10^3 g/ 10.5 mL
= 9523.809524 g/mL
Explanation:
if the first one was just O, then:
i) no of moles = mass/ molar mass
2= m/ 16
m = 16*2
m = 32g
ii) the second answer would be the same.
For the answer to the question above,
in this problem we can use the concept of freezing point depression since we are given the freezing point of the solution.
ΔT = -k(f) x m x i
-2.24 - 0 = -1.86 x m x 3
<span>m = 0.4014
</span>So the answer to your question is m = 0.4014
