Answer:17
Explanation:NH3 = 14 + 3 = 17 g/mole.
Answer:
Density (ρ) = 6820 kilogram/cubic meter
Explanation:
ρ = m/v
10.23 gram
1.5 milliliter
= 6.82 gram/milliliter
= 6820 kilogram/cubic meter
From the ideal gas law, PV = nRT, we can rearrange the equation to solve for T given the other parameters.
T = PV/nR
where P = 0.878 atm, V = 1.20 L, n = 0.0470 moles, and R = 0.082057 L•atm/mol•K. Plugging in our values, we obtain the temperature in Kelvin:
T = (0.878 atm)(1.20 L)/(0.0470 mol)(0.082057 L•atm/mol•K)
T = 273 K
So, the second answer choice would be correct.
