Determine the molarity for the following solutions. 2.0 moles of potassium iodide are dissolved into 0.10 L.

10.0 grams of potassium iodide are dissolved into 100 mL.

0.427 moles of aluminum carbonate are dissolved into 0.855 L of water.

2340 grams of aluminum carbonate are dissolved to make 1500 mL of solution.

Calculate the asked for quantity in the following solutions.
How many grams of potassium iodide will need to be dissolved to make a 100 mL of a 2.0 M solution?

You need to make a 0.5 M solution with 25.0 grams of potassium iodide. How much water do you need to dissolve it?

How many L do you need to dissolve 10.0 grams of aluminum carbonate into a 0.3 M solution?

How many grams of aluminum carbonate do you need to dissolve to make 8.0 L of a 0.75 M solution?

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.

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.
