1- We have to get the molar mass of calcium bromide, by getting the chemical formula ( CaBr2).
From the chemical formula, we have to get the molecular weight for each of Ca&Br on the periodic table:
Ca = 40.078 & Br = 79.904
* from the chemical formula ( CaBr2) so, the molecular weight of calcium bromide is:
40.078 + 2x(79.904) = 199.89
2- number of moles = weight / molecular weight
=20.275 / 199.89 = 0.1014 moles
3- where the volume of solution by littre = 575 mL/ 1000 = 0.575 L
So,
4-Molarity = moles of solute / L of solution
= 0.1014 / 0.575 = 0.1763 mol/L
It would take 1.16 h for the runner to finish the race
.
<em>Step 1. </em>Convert <em>kilometres to miles</em>.
11 km × (0.621 mi/1 km) = 6.83 mi
<em>Step 2</em>. Calculate the <em>time</em>.
Time = 6.83 mi × (1 h/5.7 mi) = 1.16 h
