The molar mass of magnesium carbonate, MgCO3, is 84 g/mole. How many moles are in 12.60 g of magnesium carbonate?
divide 12.60/84
To find the number of moles in 12.60 g of magnesium carbonate, we need to use the molar mass of MgCO3.
Given:
Molar mass of MgCO3 = 84 g/mol
Mass of MgCO3 = 12.60 g
To calculate the number of moles, we can use the formula:
moles = mass / molar mass
Substituting the given values:
moles = 12.60 g / 84 g/mol
Calculating:
moles = 0.15 mol
Therefore, there are 0.15 moles in 12.60 g of magnesium carbonate.
To find the number of moles in a given mass of a substance, you can use the formula:
Number of moles = given mass / molar mass
Here, the given mass is 12.60 g and the molar mass of magnesium carbonate (MgCO3) is 84 g/mole.
Using the formula, we can calculate the number of moles:
Number of moles = 12.60 g / 84 g/mole
Dividing 12.60 g by 84 g/mole gives us:
Number of moles = 0.15 moles
So, there are 0.15 moles in 12.60 g of magnesium carbonate (MgCO3).
