Determine the concentration of a solution made by dissolving 44.0 g of calcium chloride (CaCl2) in 0.30 L of solution. SHOW YOUR
ycow [4]

Answer:

[CaCl₂] = 1.32 M

Explanation:

We know the volume of solution → 0.30 L

We know the mass of solute → 44 g of CaCl₂

Let's convert the mass of solute to moles.

44 g . 1 mol / 110.98 g = 0.396 moles

Molarity (mol/L) → 0.396 mol / 0.3 L  = 1.32 M

The following reaction occurs in aqueous solution: NH4 + (aq) + NO2 - → N2 (g) + 2H2O (l) The data below is obtained at 25°C.
GREYUIT [131]

Answer: The order with respect to NH_4^+ is 1.

Explanation:

Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.

NH_4^++NO_2^-\rightarrow N_2+2H_2O

Rate=k[NH_4^+]^x[NO_2^-]^y

k= rate constant

x = order with respect to NH_4^+

y = order with respect to ANO_2^-

n = x+y = Total order

From trial 1: 3.2\times 10^{-3}=k[0.0100]^x[0.200]^y    (1)

From trial 2: 6.4\times 10^{-3}=k[0.0200]^x[0.200]^y    (2)

Dividing 2 by 1 :\frac{6.4\times 10^{-3}}{3.2\times 10^{-3}}=\frac{k[0.0100]^x[0.2000]^y}{k[0.0200]^x[0.200]^y}

2=2^x,2^1=2^x therefore x=  1

Thus order with respect to NH_4^+ is 1.
