The volume of a gas sample is 22.4 liters at STP. The density of the gas is 1.34 grams per liter.
lozanna [386]

Answer:

The mass of gas is 30.02 g.

Explanation:

Given data:

Volume of gas = 22.4 L

Density of gas = 1.34 g/L

Mass of gas = ?

Solution:

The given problem will be solved through density formula.

Density is equal to the mass of substance divided by its volume.

Units:

SI unit of density is Kg/m3.

Other units are given below,

g/cm3, g/mL , kg/L

Formula:

D=m/v

Now we will put the values in formula.

1.34 g/L = m /22.4 L

m = 1.34 g/L × 22.4 L

m = 30.02 g

The mass of gas is 30.02 g.

GOOD REWARD<br> I will report those who gives random answers.
Helen [10]

Answer:

3 mol AlCl₃.

Explanation:

Hello!

In this case, according to the specified reactants and products, it is possible to set up the following balanced chemical reaction:

Al(NO_3)_3+3NaCl\rightarrow 3NaNO_3+AlCl_3

Whereas we evidence the 1:3 mole ratio between aluminum nitrate and sodium chloride; thus, since different moles were reacting, we need to identify the limiting reactant by computing the moles of AlCl₃ produced by each reactant as follows:

n_{AlCl_3}^{by\ Al(NO_3)_3}=4molAl(NO_3)_3*\frac{1molAlCl_3}{1molAl(NO_3)_3} =4molAlCl_3\\\\n_{AlCl_3}^{by\ NaCl}=9molNaCl*\frac{1molAlCl_3}{3molNaCl} =3molAlCl_3

Thus, we infer that NaCl is the limiting reactant as it produces the fewest moles of AlCl₃; consequently the produced amount of this product is 3 mol.

Best regards!
