Did you ever find out the answer I'm in dier need
Answer:
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
- is a natural fibre
- has low elasticity
- is wrinkle free.
Answer:
The answer is a I think

Answer:
Ok so I dont have a paper on me, but to solve this, first you need to know, 1 ml is 1 cubic centimeter, okay so we need to find the volume, which is 4/3 times pie times r cubed, the answer to this equation will then bet 51 cubic centimeters which directly translate to 51 ml pushed out of the full cup
