Answer: Volume = 0.01L
Explanation:
The density of a substance is given by; Density = Mass / Volume.
In this question, Mass = 1000g, Volume = ? and Density = 100 Kg/L
For the units to be uniform, we convert 1000g to Kg = 1Kg
Therefore, Volume = Mass / Density = 1Kg / 100Kg/L = 0.01L
Answer:
Explanation:
E = (hc)/(λ)
E = (6.624x10^(-27))Js x ((3×10^8)ms^(-1)) /
(77.8x10^(-9)m)
E = 2.55 x 10^(-11) J
