A 1.10 mol sample of krypton gas is collected at a pressure of 427 mmHg and a temperature of 6.0°C. The volume of the sample is
Aleksandr [31]

Answer:

Volume = 44.96L

Explanation:

p = 427mmHg = 0.56atm

R = 0.08206

T 6°C = 279k

V = ?

n = 1.10 mol

using ideal gas equation

pv=nRT

0.56 x V = 1.10 x 0.08206 x 279

0.56 x V = 25.18

V = 25.18/0.56

V = 44.96L

In the reaction K2CrO4(aq) + PbCl2(aq) → 2KCl(aq) + PbCrO4(s), how many grams of PbCrO4 will precipitate out from the reaction b
Elodia [21]
The balanced chemical reaction is:

<span>K2CrO4(aq) + PbCl2(aq) → 2KCl(aq) + PbCrO4(s)

We are given the amount of the reactants to be used for the reaction. These amounts will be the starting point of our calculations. </span>

<span>
3.0 M K2CrO4 (.500 L) = 1.5 mol K2CrO4

</span>1.5 mol K2CrO4 (1 mol PbCrO4 / 1 <span>mol K2CrO4</span>) ( 323.2 g/mol)=484.8 grams PbCrO4


Therefore, the best answer from the choices is 480 grams.
