Magnesium sulfate is called Epsom salt. If one needed 4.23 moles of this compound, what mass would you need.
To solve for this problem, we need to employ the molar mass - moles ratio. Remember that:
`Number of mol es of any compound = (Given mass)/(molar mass)`
Since we are after to the given mass, we can have it as:
`Given mass = Molar mass * Number of mol es`
`Given mass = (4.23 mol es Magn esium s u l f a te)*(120.366 (grams)/(mol e))`
Given mass = 509.15 Grams Magnesium sulfate
Note: The molar mass of Magnesium sulfate is 120.366
