Thus we can balance the oxygen atoms by putting a prefix of 25/2 on the left side. To obtain a equation containing whole numbers, we multiply the entire equation by 2. This gives the final equation. 2 C8H18 + 25 O2 ---> 16 CO2 +18 H2O.

Nurse Antonio measured out 7 grams of sodium chloride (NaCI). Using dimensional analysis, calculate how many moles of NaCI he we

Neporo4naja [7]

Answer:

0.119 moles

Explanation:

Given that,

Mass measured by Nurse Antonio is 7 grams of NaCl

To find,

The no of moles of NaCl

Solution,

The number of moles is given by

$n=\dfrac{m}{M}$

m is given mass

M is molar mass

For NaCl, molar mass is 23+35.5 = 58.5 grams

So,

$n=\dfrac{7}{58.5}\\\\n=0.119\ \text{moles}$

Therefore, there are 0.119 moles of NaCl.
