What volume of 14.7 m acetic acid (hc2h3o2) contains 9.7g of acetic acid?

First, we convert grams to moles using molar mass. Then we can use stoichiometry to convert moles to liters using the knowledge that M equals moles over liters.

So, to solve:

Step 1: 9.7 g acetic acid x (1 mole acetic acid/60.05g acetic acid) x (1 L/14.7 moles acetic acid) = 0.011 L acetic acid

The real answer is keeping the world healthy so we won’t die

Answer : option a) 84explanation :

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.
