When entering a science lab which of the following should be done by science students.
D. Students must wait for their teacher to give instructions.
6. 20.0 x 17.16= 343.2m^2
I think the answer is C. C and D
Answer:
16.4moles
Explanation:
From Avogadro's hypothesis, 1mole of any substance contains 6.02x10^23 atoms.
This clearly indicates that 1mole of (NH4)3PO4 also contains 6.02x10^23 atoms.
Now, if 1mole of (NH4)3PO4 contains 6.02x10^23 atoms,
Then Xmol of (NH4)3PO4 will contain 9.87X10^24 atoms i.e
Xmol of (NH4)3PO4 = 9.87X10^24/6.02x10^23 = 16.4moles
