Question

What is the molarity of a solution when 285 grams of HCl are dissolved in 0.350L of solution?

Answer 1

Answer: 22.33 M

Step-by-step explanation:

molarity = moles of solute/liters of solution or
`M=(mol)/(L)`

first we have to find our moles of solute (mol), which you can find by dividing the mass of solute by molar mass of solute

mass of solute: 285 g

molar mass of solute: 36.46 g/mol

let's plug it in:

`(285g)/(36.46 g/mol) = 7.817 mol`

next, we plug it into our original equation:

`(7.817 mol)/(0.350 L) = 22.33 M`
