Multiply first the mass given in kilograms by 1000 in order to convert it to grams.
(0.23 kg) (1000 g / 1kg) = 230 g
Then, divide the mass in gram by the molar mass of SO2
molar mass of SO2 = 64.044 g/mol
Solving for the number of moles,
(230 g)(1 mol/64.044g) = 3.59 moles
Thus, there are approximately 3.59 moles of SO2 present in 0.23 kg of SO2.
Answer:
Nature imagery represents truth and enlightenment in Fahrenheit 451, especially for Montag, but also for Clarisse, the young woman he befriends early in the novel. Montag lives in a world where the natural has been replaced by the emptiness of the mechanical, robotic, and man-made.
Explanation:
I think it's called a Halide or a halogen
Answer:
⁵⁸Fe
Explanation:
mass number of the isotope = number of protons + number of neutrons
mass number of the isotope = 26 + 32 = 58 a.m.u
a.m.u - atomic mass units
Knowing that the element have 26 protons and 26 electrons it have to be an isotope of iron.
⁵⁸Fe
