How many grams of potassium bromide, KBr, are in 100mL of a 0.50 M solution?
VMariaS [17]

Answer:

5.95g

Explanation:

1 dm^{3} = 1000 mL

∴ 100 mL = 100 ÷ 1000 = 0.1 dm^{3}

Volume = <u>0.1 </u>dm^{3}<u />

Concentration = <u>0.5 M</u>

Concentration = \frac{No. of moles}{volume}

0.5 = \frac{x}{0.1}

No. of moles = 0.5 x 0.1 = <u>0.05 moles</u>

No. of moles = \frac{mass}{mass. in. 1. mole}

Mass in 1 mole of KBr = 39 + 80 = 119g (39 is the mass of potassium and 80 is the mass of bromine)

0.05 = \frac{x}{119}

x = 119 × 0.05 = 5.95g
