What mass of solute do you need to make 50 ml of a 20 g/L solution?
[tex]\frac{20_g}{1000_{ml}}=\frac{x_{g}}{50_{ml}}[/tex]
20 g/L = 1 g/50ml
Answer: 1 g
How many grams of solute are there in 300 g of .50% NaCl solution
[tex].50%=\frac{x_g}{300_{ml}} * 100[/tex]
[tex].005%=\frac{x_g}{300_{ml}}[/tex]
x=1.5 grams
How'd I do?
Thanks
