Iam using all my points to ask this.
a compound containing 74.0% carbon, 8.7% hydrogen and 17.3% nitrogen. determine the
empirical formula.
if the compound above has a molar mass of 162.1g/mol. determine the molecular formula of the compound

C5H7N

C10H14N2

Explanation:

ok so lets lay out this nicely

elements                                                         C              H         N                    

percentage                                                    74             8.7       17.3

mass number                                                 12              1          14

divided percentage by mass                        6.167          8.7      1.2357

now divide the smallest number with the 4.99            7.04    1

rest for instance 1,237 is the smallest.    

so 6.167÷1,237

and 8.7 ÷1.237

and 1,237 divide 1.237    

now the ratio is                              C5H7N

now for molecular formula find Mr of C5H7N which is (12×5)+7+14=81

next divide 162.1÷81=2

so now for molecular formula just multipily everythng by 2

C10H14N2

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.
