When a piston with a volume of 35 mL is heated from 298 K to 596 Kit
expands. Assuming the pressure on the piston remains constant, determine
the new volume of the cylinder. (round to the nearest whole number)
no
Explanation:

Matter is made of very tiny particles. One mole of a substance contains a given amount of particles. This number is constant for all particles- 6.022×10^23<span> , and is called Avogadro's constant. To get the number of particles in 4g of butane, we need to calculate the number of moles represented by 4 g, then multiply by the Avogadro's constant (Since each mole has particles equivalent to the Avogadro's constant)
Therefore, if 1 mole = 58.1g
how many moles will be equal to 4g?
we cross multiply (4x1) divide by 58.1
equals 0.068847moles
multiply by Avogadro constant = 4.1466 x 10^molecules
But remember the question is not about the number of molecules in butane, its about the number of carbon atoms.
Since there are four carbons in butane, and each has </span> 4.1466 x 10^22 atoms
to get the number of atoms, we multiply by four
equals 1.6586 x 10^atoms
The balanced chemical equation will b
N2H4 + 2 H2O2-> N2 + 4H2O
so first of all we have to find the limiting reactant.
so for this
9.24 g H2O2 ( 1 mol / 34.02 g mass of H2O2 )
= 0.27 mol H2O2
Now
6.56 g of N2H4 ( 1mol / 32.06) = 0.20 mol N2H4
so from the above reaction we found 1:2 ratio of the reactants
so the limiting reactant is hydrogen peroxide. by using this we will find the amount of N2 produced.
so that will be
<span>0.27 mol H2O2 ( 1 mol N2 / 2 mol H2O2 ) ( 14.01 g N2 / 1 mol N2)
=1.89 g N2
