gm/l = molecular weight* molarity

So, here the molarity of h2so4 is 2M given. And we know the molecular weight of h2so4 i.e 98amu;

Then , gm/l =98*2 = 196

What is the total number of liters of SO3 produced when 32.0 of SO2 reacts completely

ahrayia [7]

Write the chemical equation for reaction
that is
2SO2+O2 --->2SO2

find the moles of SO2 used = moles=mass/molar mass of so2

= 32g/80g/mol=0.4 moles

by use of reacting ratio between SO2 and SO3 which is 2:2 therefore the moles of so3 is also = 0.4 moles

STP 1 mole = 22.4L.
what about 0.4moles

= 0.4 /1 x22.4=8.96 liters

The reactants of two chemical equations are listed. Equation 1: PbNO3 + Mg Equation 2: PbNO3 + KI Based on the type of reaction,

Vika [28.1K]

Answer:

Equation 2, because K being more reactive, exchanges position with Pb in PbNO3.

Explanation:

Hello there!

In this case, according to the given reactions, it is possible to realize that according to the reactivity series, since K is is group 1A of alkali metals, we infer it is by far more reactive than magnesium, for that reason last two choices can be easily discarded. Now, considering equation 2, it would be necessary to complete it to figure out the correct option:

$Pb(NO_3)_2 + KI \rightarrow PbI_2+KNO_3$

Whereas it can be seen that potassium exchanges position with Pb according to the double displacement reaction; therefore, the correct answer is "Equation 2, because K being more reactive, exchanges position with Pb in PbNO3".

Best regards!

Diphosphorus pentoxide(P2O5) reacts with water to form phosphoric acid, a major industrial acid. In the laboratory, the oxide is

Akimi4 [234]

Answer: The mass of $4.65\times 10^{22}$ molecules of phosphorus pentoxide is 20.5 g

Explanation:

According to avogadro's law, 1 mole of every substance weighs equal to the molecular mass and contains avogadro's number $6.023\times 10^{23}$ of particles.

To calculate the moles, we use the equation:

$\text{Number of moles}=\frac{\text{Given molecules}}{\text {avogadro's number}}=\frac{4.65\times 10^{22}}{6.023\times 10^{23}}=0.0772moles$

1 mole of $P_2O_5$ weigh = 283.9 g

Thus 0.0772 moles of $P_2O_5$ weigh = $\frac{283.9}{1}\times 0.0722=20.5g$

Thus the mass of $4.65\times 10^{22}$ molecules of phosphorus pentoxide is 20.5 g
