I cant see the units properly. You can try using E = hf, where h is the Planck's constant and f is the frequency that you need and E is the energy released in the transition.

Jones Soda contains 33g added sugar (C6H12O6) in a 355 ml bottle, while Sierra Mist contains 62g added sugar in a 591 ml bottle.
ArbitrLikvidat [17]

C6H12O6 molar mass: 180.15768 g

solute: sugar

molarity = moles of solute / liters of solution

Jones Soda:

33 g / 180.15768 g = 0.18 moles C6H12O6

M = 0.18 g / 0.355 L

M = 0.52

Sierra Mist:

62 g / 180.15768 g = 0.34 moles C6H12O6

M = 0.34 g / 0.591 L

M = 0.58

Sienna Mist has a higher molarity and is more concentrated.

What is the mass number of an atom with 17 protons, 17 electrons, and 20 neutrons?
astra-53 [7]
The mass number of this particular element is 37

An element with 17 protons will ALWAYS be chlorine.
The mass number is found by adding the element’s protons and neutrons.
protons+neutrons=mass number

Here is the math if needed,
17+20=37

Therefore the mass number is 37

I hope this helped!
