Step 1 : write a valanced equation..
NaOH + HCl 》NaCl + H2O
Step 2 : find the number of mole of HCl..
1000 ml ..contains 4.3 mole
15ml... (4.3÷1000)×15 =...
Stem 3 : use mole ratio....
HCl : NaOH
1 : 1
So mole is same as calculated above...
Step 4 :
3.5 mole of NaOH is in 1000ml
(4.3÷1000)×15 mole is in ....
Do the calculation
Answer:
Measuring the Volume of Solids
Rectangular prism - Multiply the measurement of the length times the width, then times the height.
Cube - Since all sides are the same measurement, it would be the measurement of any side, or edge, cubed, or a³
Explanation:
Answer:
The number of moles of O atom in
mol of
= 1.6
Explanation:
1 molecule of
contains 2 atoms of O
So,
molecules of
contains
atoms of O.
We know that 1 mol of an atom/molecule/ion represents
numbers of atoms/molecules/ions respectively.
So,
molecules of
is equal to 1 mol of
.
atoms of O is equal to 2 moles of O atom.
Hence, 1 mol of
contains 2 moles of O atom.
Therefore,
mol of
contains
moles of O atom or 1.6 moles of O atom.
