Answer: 401.4g
Explanation:
The mass can be calculated by using the following mathematical expression for Moles ,which is:
Moles = Mass / Molar Mass
From the question given, Moles = 1.72, Molar mass of BaSO4 = 233.38g/mol, Mass =?
Making 'Mass' the subject of formula, we get:
Mass = Molar mass x Moles
= 233.38 x 1.72 = 401.4g
Answer: Thus there are 88.4 g of calcium bromide.
Explanation:
According to avogadro's law, 1 mole of every substance weighs equal to the molecular mass and contains avogadro's number 
of particles.
Molar mass of = 40.1 (1)+ 2(79.9) = 199.9
To calculate the moles, we use the equation:
Thus there are 88.4 g of calcium bromide.
