Concentrations and Units Practice

You have $25g$ of IBA $($an auxin used in rooting cuttings$)$ in $1\mathrm{.}5$ liters of water. The molecular weight of IBA equals $203\mathrm{.}2g.$ For water, $1L=1kg$

a$.$ Express the concentration as a percent.

b$.$ Express the concentration in ppm$.$

c$.$ Express the concentration in molarity $($M$).$

You have $32g$ of NAA $($an auxin used in rooting cuttings$)$ in $3$ liters of water. The molecular weight of NAA equals $186\mathrm{.}21g.$

a$.$ Express the concentration as a percent.

b$.$ Express the concentration in ppm$.$

c$.$ Express the concentration in $m\frac{g}{L}.$

d$.$ Express the concentration in molarity $($M$)$

What Molarity is $1569g{H}_{2}S{O}_4($sulfuric acid$)$ in $1$ liter of water?

You need to make a $1500ppm$ solution of $G{A}_3.($Molecular weight of $G{A}_3$ is $346\mathrm{.}4g*mo{l}^{-1}).$

a$.$ How many $mg$ do you need to weigh out to make $1$ liter of solution?

b$.$ What is the molarity of this solution?

How many grams of IBA does $1,000g$ of a $2\%$ solution contain?
