What mass of solute do you need to make 50 ml of a 20 g/L solution?(adsbygoogle = window.adsbygoogle || []).push({});

[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
