Use ideal gas equation: pV = nRT
Now pass n to mass: n = mass / MM .... [MM is the molar mass]
pV = [mass/MM]*RT =>mass/V = [p*MM] / RT and mass / V = density
p= 130 kPa = 130,000 Pa = 130,00 joule / m^3
T = 10.0 ° + 273.15 = 283.15 k
MM of sulfur (S) = 32 g/mol = 32000 kg/mol
density = 130,000 Pa * 32000kg/mol / [8.31 joule / mol*k * 283.15 k] = 1.77*10^6 kg/m^3 = 1.77 g/L ≈ 1.8 g/L
Then, I do not get any of the option choices.
Is it possbile that the pressure is 13.0 kPa instead 130. kPa? If so the answer would be 18 g/L
Note that the mass is not used. You do not need it unless you are asked for the volume, which is not the case.
Some fuels are used to better suit vehicles, while other types of fuels are used to reduce carbon emmision, e.t.c.

Mass number = number of protons + number of neutrons
number of protons = atomic number =7
number of neutrons= mass number - number of protons=16-7=9
Answer is B.9.
Answer:
0
Explanation:
If you mix NH3 and H2O the reaction is NH3 + H2O → NH4OH not NH3OH.
Te equation, like that is balanced. There is 1 N, 5H and 1 O in the reactives and 1 N, 5 H and 1 O so you have the same number of elements in the reactives and products, thus it's balanced and you don't need to do anything
This type of questions is relationed with REDOX balanced
