How many grams of glyoxylic acid and sodium glyoxylate are needed to prepare 1.75 L of a 2.10 M buffer at pH 3.35 ? The pa of glyoxylic acid is 3.34 . Note: Use the monohydrate forms, HCOCO2H⋅H2O and HCOCO2Na⋅H2O

both glyoxylic acid needed in grams and sodium glyoxylate needed in grams

the answer is 1 i believe

idk what the question is about

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.
