Answer:
The mass of solid with density 14.2 g/cm3 and volume 350 cm3 is 4.97 Kg.
Explanation:
Formula for density is given below :



Insert the values in the formula

on cross multiplication :



1 g = 0.001 Kg

mass = 4.97 Kg
Note : Check the units of volume and density carefully
I believe its 10^23 u r saying
then no. of moles= 9.03*10^23/6.02*10^23=1.5mole
Answer: 1. P1V1 = P2V2
2. P stands for pressure
3. Units for Pressure are atm and Pa
4. V stands for volume
5. Units for volume is in mL
Explanation: Boyle's Law is a gas law that states the relationship between pressure and volume of a gas.
The free energy change(Gibbs free energy-ΔG)=-8.698 kJ/mol
<h3>Further explanation</h3>
Given
Ratio of the concentrations of the products to the concentrations of the reactants is 22.3
Temperature = 37 C = 310 K
ΔG°=-16.7 kJ/mol
Required
the free energy change
Solution
Ratio of the concentration : equilbrium constant = K = 22.3
We can use Gibbs free energy :
ΔG = ΔG°+ RT ln K
R=8.314 .10⁻³ kJ/mol K
