How to solve 5gNaCl= MolE NaCl
valentinak56 [21]

0.086mole

Explanation:

The problem is very simple. It involves conversion from mass to number of moles of NaCl

What is mole?

 A mole is a unit of measuring chemical substances. It is the amount that contains the avogadro's number of particles.

How is it related and can be converted from mass;

 

Number of moles of a substance = \frac{mass}{molar mass}

Since we know the mass, we can find the molar mass and put into this equation;

Molar mass of NaCl = 23 + 35.5 = 58.5g/mol

Number of moles of NaCl = \frac{5}{58.5}  = 0.086mole

How many moles are in 15.5-g SiO2
DochEvi [55]

Answer:

0.26 moles

Explanation:

Number of moles = mass/molar mass

Mass of SiO2 = 15.5g

Molar mass of SiO2 = 60.08g/mol

Number of moles = 15.5g/60.08g/mol

=0.257

= 0.26 moles
