Answer:

6.022x10^{23}atoms \ Al

Explanation:

Hello,

In this case, given the described concept regarding the Avogadro's number, we can easily notice that 27.0 g of aluminium foil has 6.022x10²³ atoms as shown below based on the mass-mole-particles relationship:

27.0gAl*\frac{1molAl}{27.0gAl} *\frac{6.022x10^{23}atoms \ Al}{1molAl} \\\\=6.022x10^{23}atoms \ Al

Notice this is backed up by the fact that aluminium molar mass if 27.0 g/mol.

Best regards.

What is the mass of a 300 ml sample of gaseous hydrogen chloride at 2.0 atm and 30c?
kap26 [50]
Use PV = nRT
(2 atm)(.3 liters) = n(8.314 mol*K)(303°K)

.6 = n(2519.142)

Divide by 2519.142

n = .00023818 mols of HCl * 36.46g of HCl/ 1 mol of HCl

Grams of HCl = 0.00868

Balance the equation for the reaction of benzene and hydrogen to form cyclohexane.. C6H6 + H2 → C6H12.
Vedmedyk [2.9K]
Here is a universal law to balance chemical equations :
All chemical equations must be balanced because of the law of conservation of mass.
It states that "matter cannot be created or destroyed."
So, the number of atoms that you start with at the beginning of the reaction must equal the number of atoms that you end up with.
 keeping this law in our mind,lets balance the<span> equation for the reaction of benzene and hydrogen to form cyclohexane.
