1. Assuming that it behaves ideally, what will its new volume be? The first step is to ensure that the pressures and temperatures are in absolute units. The pressures are quoted in bara, which means that the values are absolute. However we will have to add 273 to the temperatures to convert them from ˚C to K.

2. Carbon has an atomic mass of 12 atomic mass units (a.m.u.). Hydrogen has an atomic mass of 1 (a.m.u.).

μ_н = [0.658 * ρ_н ² / (10 ³ * 886 - ρ_н ²)] ²;

μ_t = (1 / С) * (С*μ_to)^φ

φ = 1 / (1 + а(t - t_o) lg (C*μt_o));

С = 100 1 / мПа*с; а = 1.44 * 10 ^-3 1/^оС

М_н = 0.2*ρ_o*μ_o^0.11 молярную массу сепарированной нефти

ρ_вп = ρ_в + 0.7647*S ρ_в — плотность дистиллированной воды при 20 ^оС, кг/м³; S –концентрация соли в воде (растворе), кг/м³.
