Answer:
hey :)
your answer is D.
Explanation:
To find density, you must divide mass and volume.
8 divided by 4 is 2
6 divided by 6 is 0
4 divided by 2 is 2
hope i helped any :))
I believe the correct answer is the first option. To increase the molar concentration of the product N2O4, you should increase the pressure of the system. You cannot determine the effect of changing the temperature since we cannot tell whether it is an endothermic or an exothermic reaction. Also, decreasing the number of NO2 would not increase the product rather it would shift the equilibrium to the left forming more reactants. The only parameter we can change would be the pressure. And, since NO2 takes up more space than the product increasing the pressure would allow the reactant to collide more forming the product.
So, you need to have same ammount of atoms on the left and on the right side of the equation. You need to count the ammount of attoms of every substance on the left, and make sure that on the right side the ammount is same. For example in the 1st one it’s 6Sn+2P4=2Sn3P4, so that you have 6atoms of Sn on the left and 6 atoms of Sn on the right, same with the P
Density is weight by volume.
First. If you divide the weight by density you can find the volume
Second you must convert the ML in to Liters.

1L=1000ml


0.38214 Liters.
