How many grams of salt, sodium chloride, are contained in 1000.0 mL of ocean water, if the concentration is 0.

Question

How many grams of salt, sodium chloride, are contained in 1000.0 mL of ocean water, if the concentration is 0.60M?

Answer 1

Na= 23, Cl=35.5

1 mole of NaCl = 58.5g/l

1 litre = 1000ml

to determine 0.6Moles

(0.6moles/1mole) x 58.5

>>>>> Answer = 35.1g

Answer 2

well, first off whenever you see something like 0.60M it means, in this case, 0.60 moles per liter
1000.0 mL is equal to 1 L therefore 0.60 mol / 1 Liter means you have 0.60 moles in the sample of ocean water.
to find the amount in grams you would use the molar mass, 58.4 g NaCl / 1 mol NaCl
0.60mol NaCl x 58.4 g NaCl / 1 mol NaCl =35.04g NaCl or salt

Answer 3

Atomic weights: Na=23 Cl=35.5 NaCl=58.5
Let ocean water be called W; let salt be called S

1000mL-W x 0.60M-S/1000mL-W x 58.5gS/1molS = 35.1gS
