Explanation:
The dimensions of a standard backpack is 30cm x 30cm x 40cm
The mass of an average student is 70 kg
We know that, the density of gold is 19.3 g/cm³.
Let m be the mass of the backpack. So,
An average student has a mass of 70 kg. If we compare the mass of student and mass of backpack, we find that the backpack is 10 times of the mass of the student.
Here's The Answer: <span> K = 50.2 = (2x)^2 / (0.1-x)^2
x = 0.078
so H2 eq = 0.022 M
Hope this helped! :D

Moles of water atoms = mass/molecular weight = 105/18 = 5.83 mol. Number of moles of hydrogen in water = 2 x moles of water = 11.66. Number of H atoms in water = moles of hydrogen x 6.02 x 10^23 = 7.019 x 10^24 ~ 7.02 x 10^24 atoms. Hope this helps.
False, if you compare how spread apart the molecules in liquids are compared to gases and solids, liquids would be in the middle. They aren’t very spread apart, per say, but they aren’t compact since water is not very dense.
Good the equation is balanced already
