Suppose you wanted to dissolve 109 g of sodium carbonate in enough water to make 6.00 L of solution. What is the molarity of this solution?
Answers
Molarity
a. Na2CO3 Molar mass = 106 g/mol n= 109 g / (106 g/mol) = 1.028 mol
b. 6.00L
c. M=n/V M = 1.028 mol / 6.00 L M= 0.1713 mol / L
Answer: The molarity of the sodium carbonate solution is 0.1713 mol/L
How many grams are there in 3.5 moles of H20
Answers
Molar mass H₂O = 18.0 g/mol
1 mol ----- 18.0 g 3.5 moles --- ?
Mass ( H₂O) = 3.5 x 18.0 / 1
=> 63.0 g

How many significant figures does 546.000 have
Answers
This has only only three sig figs because it is 546.000 the zeros are just place holders so thus meaning they are not significant. It is just another way to write 546 because in that number there is also 3 sig figs. They are just trying to throw you off. Just watch out because if the example is 540 then it is just two significant digits, and it were to be 540. then it be three cause that "." makes the zero significant.
