What would the volume (L) of 6.6 g of CO2 be if it were measured at the same temperature and pressure as that of the experiment

(only 2 decimal places are needed)? Enter only the number of liters; do NOT include the "L" for liters.

Answer:

The correct answer is 3.36 L

Explanation:

The molecular weight of CO₂ is 44 g/mol (2 O + 1 C= (2 x (16 g/mol )) + 12 g/mol). We have 44 g in 1 mol CO₂, and we want to know how many mol are in 6.6 g:

44 g -------------- 1 mol CO₂

6.6 g -------------- X= 6.6 g x 1 mol / 44 g = 0.15 mol

In normal conditions of temperature and pressure, 1 mol of ideal gas occupies 22.4 L of volume, thus:

1 mol CO₂ ------------ 22.4 L

0.15 mol -------------- X= 3.36 L

So, 6.6 g CO₂ are equivalent to 0.15 mol CO₂ and they occupy 3.36 L.

Law of Conservation of Mass in terms of atoms
VARVARA [1.3K]

No atoms are lost or made during the chemical reaction so the total mass of the products is equal to the total mass of the reactants. In an atom, protons and neutrons contribute to the mass and since the number of them doesn’t change, the mass doesn’t either.

what is the best course of action if solid material remains in the flask after the heating step of recrystallization
lys-0071 [83]

Answer:

filter the hot mixture.

Explanation:

Solid is stayed undissolved since the arrangement is gotten super saturated. On the off chance that solid molecule is available recrysallization won't happen in this way we need expel the solid molecule by filtarion in hot condition itself . Subsequently, arrangement become totally homogenous and recrysallization item will shaped by moderate cooling
