Answer:

Solvent

Explanation:

Many people use the solute to describe the solid being dissolved and the solvent to describe the thing doing the dissolving, but really solvent means the part of the solution with a greater amount/concentration.

For example, if you have 1 gram of salt in 10 liters of water, the water is the solvent.

The empirical formula for a compound is ch2o and the molar mass is 180.2g mol which is molecular formula for this compound
elena-14-01-66 [18.8K]
Answer:
                Molecular Formula  =  C₆H₁₂O₆

Solution:

Molecular formula is calculated by using following formula,

                     Molecular Formula  =  n × Empirical Formula  ---- (1)

Also, n is given as,

                      n  =  Molecular Weight / Empirical Formula Weight

Molecular Weight  =  180.2 g.mol⁻¹

Empirical Formula Weight  =  12 (C) + 2 (H₂) + 16 (O)  =  30 g.mol⁻¹
Son
                      n  =  180.2 g.mol⁻¹ ÷ 30 g.mol⁻¹

                      n  =  6

Putting Empirical Formula and value of "n" in equation 1,

                     Molecular Formula  = 6 × CH₂O

                     Molecular Formula  =  C₆H₁₂O₆

If a balloon containing 3000 L of gas at 39°C and 99 kPa rises to an altitude where the pressure is 45.5 kPa and the temperature
ludmilkaskok [199]

\tt =3000~L\times \dfrac{289}{312}\times \dfrac{99}{45.5}

<h3>Further explanation</h3>

Given

3000 L of gas at 39°C and 99 kPa to 45.5 kPa and 16°C,

Required

the new volume

Solution

Combined with Boyle's law and Gay Lussac's law  

\tt \dfrac{P_1.V_1}{T_1}=\dfrac{P_2.V_2}{T_2}

T₁ = 39 + 273 = 312

T₂ = 16 + 273 = 289

Input the value :

V₂ = (P₁V₁.T₂)/(P₂.T₁)

V₂ = (99 x 3000 x 289)/(45.5 x 312)

or we can write it as:

V₂ = 3000 L x (289/312) x (99/45.5)
