If both objects have the same volume, but a different weight, than the densities are different. One has the greater density, while the other doesn't.

Explanation:

Density of a substance is defined as mass divided by its volume.

Mathematically, Density = $\frac{mass}{volume}$

So, density is proportional to the mass of substance. Hence, an increase in mass will lead to increase in density of the substance also.

Whereas density is inversely proportional to volume of a substance. Hence, an increase in volume will lead to a decrease in density of the substance.

So, when densities of two objects that have the same volume, but one feels heavier than the other then it means mass of one object is greater than the other.

Hence, density of one object is greater than the other. That is why, one feels heavier than the other.

Calculate the enthalpy of the formation of butane, C4H10, using the balanced chemical equation and the standard value below:

zavuch27 [327]

Answer:

+125.4 KJmol-1

Explanation:

∆H C4H10(g) = -2877.6kJ/mol

∆H C(s)=-393.5kJ/mol

∆H H2(g) = -285.8

∆H reaction= ∆Hproducts - ∆H reactants

∆H reaction= (-2877.6kJ/mol) - [4(-393.5kJ/mol) +5(-285.8)]

∆H reaction= +125.4 KJmol-1

How many moles are present in 3.4 x 1023 atoms of Na?

Andrej [43]

<h3><u>moles of H2SO4</u></h3>

Avogadro's number (6.022 × 1023) is defined as the number of atoms, molecules, or "units of anything" that are in a mole of that thing. So to find the number of moles in 3.4 x 1023 molecules of H2SO4, divide by 6.022 × 1023 molecules/mole and you get 0.5646 moles but there are only 2 sig figs in the given so we need to round to 2 sig figs. There are 0.56 moles in 3.4 x 1023 molecules of H2SO4

Note the way this works is to make sure the units are going to give us moles. To check, we do division of the units just like we were dividing two fractions:

(molecules of H2SO4) = (molecules of H2SO4)/1 and so we have 3.4 x 1023/6.022 × 1023 [(molecules of H2SO4)/1]/[(molecules of H2SO4)/(moles of H2SO4)]. Now, invert the denominator and multiply:
