Convert each quantity to the indicated units. a. 3.01g to cg. b. 6200m to km

miss Akunina [59]

a. 301 cg

b. 6.2 km

Explanation:

a. knowing that 1 gram (g) is equal to 100 centigrams (cg) we devise the following reasoning:

if 1 g is equal to 100 cg

then 3.01 g are equal to X cg

X = (3.01 × 100) / 1 = 301 cg

b. knowing that 1 kilometer (km) is equal to 1000 meters (m) we devise the following reasoning:

if 1 km is equal to 1000 m

then Y km are equal to 6200 m

Y = (6200 × 1) / 1000 = 6.2 km

What is the molarity when water is added to 4 moles of sodium chloride to make 0.5 liter of solution?

loris [4]

If 0.5 L of solution contains 4 mol
then let 1 L of solution contain x mol

⇒ (0.5 L) x = (4 mol) (1 L)

x = (4 mol · L) ÷ (0.5 L)

x = 8 mol

Thus the molarity of the Sodium Chloride solution is 8 mol / L OR 8 mol/dm³.
