Light travels in a straight line as a wave. It does not require any medium or material to travel like sound waves which means it can travel in vacuum.The speed of the light from the special theory of relativity is a constant value of 38x10^8m/second
Answer:
Molarity of Limonol is
M = 1.43mol/L
Explanation:
M = mols/L
mols = g/molar mass
Therefore, determine molar mass, divide into grams luminol and divide that by 75 mL (in liters) to obtain molarity = M.
Molar mass of Limonol = 177.16 g/mol
mols = 19g / 177.16 g/mol
mols = 0.1072mol
Molarity of Limonol, M = 0.1072 mol / 0.075
M = 1.43mol/L
Mole is equal to mass of the element divided by molar mass of the element. that is
mole=mass/molar mass
From periodic table calcium has a molar mass of 40 g/mol
moles is therefore =800g/40g/mol=20moles
