If you have 12.0 moles of sulfuric acid in a bottle, in solution with water, and the volume of the solution is 2.00 L, what's the sulfuric acid's molarity?*
14.0 M
0.167 M
10.0 M
.00 M

what is the general relationship between a galaxy's distance from earth and its speed?

the answer is:

the farther away a galaxy is from us, the faster it is moving away from us.

the answer to this question is 3.

that's what i got you can count the number of atoms

considering the question as per the attachment

here we can see that the radon nuclide has 222 as the atomic mass number and 86 as the atomic number.

when it undergoes nuclear fission it gives polonium which has atomic mass number as 218 and atomic number will be 84 along with a helium nucleus which has 4 atomic mass number and 2 as its atomic number.

222 = 218 + 4 (atomic mass number)

86 = ? + 2; therefore ? = 86-2 = 84.

the atomic mass number of polonium will be 84.
