To calculate the molarity (M) of a solution, you use the formula:
M = moles of solute / volume of solution in liters
From the information provided, you have 7.0 moles of solute and a solution volume of 569 mL. First, convert the volume from milliliters to liters because molarity is expressed in moles per liter. There are 1000 milliliters in 1 liter, so:
569 mL * (1 L / 1000 mL) = 0.569 L
Now, using the molarity formula:
M = 7.0 moles / 0.569 L = 12.3 M (rounded to two significant figures)
So, the molarity of the solution is 12.3 M.
